I recently published this book on KDP. It’s a fantasy novel in which the three main characters each have their own story lines. There’s a soldier, a Witch, and an assassin. Slowly, the three stories converge, which is why I wanted to include the three images (each is loosely related to each of the three characters).

Nathan says:

I think the idea of a triptych cover could work, but you need to make sure that each of the images is instantly identifiable, even trimmed down, even in thumbnail.  Looking at at the thumbnail here, you can see that the eye is the only image that can immediately be recognized as what it is, maybe.

However, you’re making your work harder for yourself by giving even less real estate for the triptych images to occupy.  The landscape serves little purpose at the bottom, and the accompanying sky serves even less purpose at the top. It’s just wasted space.

Your small title (and teeny byline) become nigh-on invisible against that background, both because of the thin letters against an image with texture, and because of the lack of value contrast (light/dark) with the image behind the type.

It’s a cover that makes the potential reader work to get anything out of it, and since said potential reader will likely see this with other book covers to the left and right, you can’t afford not to engage the reader as quickly and as clearly as you can.

Claire has lived most of her life enslaved by a dark mage and his monstrous creatures. As a special skill slave, Claire is frequently put into life or death situations with only her wit to keep her alive. In secret, she is given a mystical necklace with unusual properties, a necklace that is one of six and together it is said they have the power to free her people. But first, she has to escape her prison. Claire’s journey begins before she even knows it’s started and her path is flanked by dangers and mysteries. She will discover things about herself and her world that she would never have believed possible. A mysterious light, A fight for freedom, And a journey to change her world.

Nathan says:

The description makes clear that it’s fantasy, but doesn’t really tell us about the setting (the fact that the name “Claire” is in modern usage compounds the problem); I can only assume from elements in the image that it’s a vaguely pre-modern second-world fantasy setting.

First up, I have some complaints with the image; it’s fairly well done, but that right arm does a lot of damage; it seems out of proportion to the rest of the female model (to the point of seeming male), the forearm has obviously been painted in Photoshop, and it almost completely hides the sword, which is the only element which would say “fantasy” on first glance.  Given that it looks like the right arm was added to the image after the fact, I’d love to see how the image looks with the arm removed.

I think you’ve also got a lot of margin going to waste; the black empty space seems not so much an intentional design choice as simply an unwillingness to have any more overlap than necessary. You could easily cut the illustration down this much:

…and still be able to put the title and subtitle across the top and the byline across the bottom without obscuring any central detail.  We don’t really need to see her hands clearly to know they’re there, after all.

And I don’t love that font; it seems to take up lots of space without giving a good return in impact, and seems like the kind of font that would be chosen by convenience (or desperation) than by positive appeal.

This for a romantic thriller or romantic suspense. While vacationing on a train journey across Europe, a feisty ATC is forced to work with a tenacious FBI agent to prevent a series of deadly terrorist explosions she is triggering against her will.

Nathan says:

It’s a very well done illustration, but it doesn’t seem right for this book.  I’m not sure what an “ATC” is (air traffic controller, maybe?), but with FBI agents and bombs involved, I’d expect to see a gun or other sign of action and violence.  This gives more of the impression of a modern “gothic” novel — dramatic and possibly perilous, but the heroin is without defense.

The other problem with the illustration is that it doesn’t allow clear areas for text, meaning that the title and byline (and subtitle and tagline) all have to be squeezed into odd spaces.

(Of the utterly boring character of the font used for all text, we shall not speak).

Local TV news reporter deals with a worldwide plague of antibiotic resistant bacteria, a conspiracy to cover up a new skin disorder in children, and his old high school nemesis forcing himself back into his life.

This is my newest proof-of-concept for this book. I took the advice of others and tried to mimic books from the Medical Thriller genre’. Keeping the background a solid white, however, just looked too sterile, so I added a grainy texture to it. And sorry to all those who preferred the round bacteria over the pill shaped ones, but google-searching images of specific antibiotic resistant germs displayed more of this style then the others. Besides, I believe the round ones look more stationary and docile while the long ones look active and aggressive.

It… looks like a cross between a pickle, a tampon, and a sperm.

I think you’re moving in the right direction, but it needs a lot more refinement.

• I don’t know why, but it seems that a taller font (usually sans serif, but not always) works for the medical thriller genre.
• With the, um, ease with which the image of the germ could be misinterpreted, a visual cue that we’re looking at something microscopic would help a lot. Googling “view through a microscope” shows me this:

I think showing the blurry circle of the microscope is the main visual cue missing.

Put that together with your revised image, and here’s a five-minute redo:

I’m not happy with how the microscope effect turned out — I’d want to refine it to make it more immediately recognizable as such — and the font is the first tall one I came across, but hey, five minutes.

Genre: Cyberpunk, Sci-fi.

Comparable book: Series-Neuromancer,

This book-LitRPGs books Publishable, but looking for feedback on the characters. As everything is pretty much silhouettes I worry the characters blend in too much. I’ve tried a couple variations and this is the best of the lot. I’ve tried a gradient from orange to black, but it feels like they pop too much. Or, is this even the right direction with characters?

Elevator pitch: In the second novella, a night of playing a VRMMORPG turns dark when one of Ragan’s friends doesn’t wake up after being captured by a raid boss. Using her skills as computer security cracker she will have to figure out what is trapping people in the game, and for what reason before time runs out.

Nathan says:

Your intuition is right: The characters blend too much.

I think the fix on that, though, needs to go back further into the design.  You’ve got way to much unused space (which is not the same as functional empty space, i.e., a conscious decision to use a blank spot as a design element).  Look how much everything on the cover is improved by cropping:

(I know, I cropped off the byline. I’m not on my home computer right now, so I can’t modify the image beyond a few basics.)

Once you do that, EVERYTHING becomes clearer.  When you put the byline across the characters’ legs, you can then increase the intensity of the glow around the silhouettes, and it won’t look out of place.

Also: Have you considered rendering the grid on the bottom in green?
