A short erotic thriller focused on an innocent girl being drawn into her boyfriend’s wealthy family and discovering their dark and twisted sexual relationships.

Nathan says:

The biggest problem here is that you’ve chosen an image with the girl as the aggressor; that sounds like the complete opposite of what you want.  Start with a different image, on in which the female figure is in sexy peril.

The book blurb for what it’s worth: Sometimes you have to break in in order to break out… Raphael, the world’s first superintelligent AI, has gone missing from its lab. If the security tapes are to be believed, it has simply vanished into thin air. A case of tech-theft or something far more sinister? Its creator, Andy, has complete faith in the security protocols he built into his AI, but others are not convinced. Confined to his home, he is now in a race against time to set things right, all the while staying one step ahead of the skulduggery and infighting within a company that seeks nothing less than control of the new economy. Dive into trolley problems and machine morality in this sci-fi howdunnit of Ex Machina meets Rear Window as you try to figure out whether Raphael is a guileless automaton or a monster that will do anything to get what it wants.

Gosh, it does my heart good when someone submits a cover, gets constructive feedback, and follows through on that feedback. Well done.

My two comments:

• The way the title overlaps the sun’s glow is a little awkward; I would either tweak the layout to get rid of the overlap, or add a dark outline to the title to separate the red of the title from the orange of the sun.
• I would both enlarge and separate the robot and wheelchair figures, letting each take up more real estate closer to the edges. Especially with the robot, there’s nothing to be gained by leaving all that blank space behind it.

(Prototype with two possible versions; has Shutterstock watermarks.) This is a 32K word story in the “LitRPG” or “GameLit” genre in which characters are playing some sort of roleplaying game with specific rules. Similar authors: Michael Chatfield, M. H. Johnson, Travis Bagwell. In this one, there’s a post-apocalyptic (21st century) village. Its people learn about a tower built by a game-obsessed AI who challenges them to go there and fight their way to the top, past robots.

Nathan says:

If you’re going for a post-apoc vibe, the second cover is DEFINITELY the way to go.  Not only is the figure drawing on the first cover a little off (perspective is hard), the initial impression is one of fantasy, not sci-fi — you have to look longer to realize that there’s actually some tech in the faery-like body armor.

Concentrating on the second cover: I’d see what can be done about making the title bigger; having title and byline the same size is visually confusing, and unless your name is “Stephen King” etc., it’s the title that should probably be larger.

The two layouts I’d play with are one with the title at the top (on two lines), and the subtitle left-justified to the left:

…or maybe subtitle at the very top, and title to the left in that open space, left-justified:

A collection of short erotic stories which, broadly, have some religious element in them.

Nathan says:

Well, you’ve definitely overcome the problem of “not sexy enough” on your last cover!

I think that, if the religious element is part of the appeal, it needs to be played up more. Romance novels often use religious terms like “sin,” “heaven,” “angel,” “devil,” etc. in their titles, so that alone doesn’t really give the reader an inkling of religious flavor in these stores. I think adding some gentle religious imagery to the background might help, like so:

I don’t think this particular fresco works especially well — it’s just one I grabbed from Google as a demo.

Inspired by escape rooms, Puzzling Escapes locks the reader in a fascinating and rich scenario full of riddles and clues. You and your friend Astrid decide it would be fun to investigate an abandoned spaceship. But as soon as you’re inside, the doors lock and the power fails. Can you find all the clues and solve each puzzle?

Last time I submitted a cover for this book, I leaned heavily on the space aspect. After much back and forth, I wanted to try a cover which looks much more like a typical puzzle book. Some of the tropes I tried to include are bold solid colors, simple font treatment, a more descriptive title, and the simple geometric design.

The only thing I’m going to say is that the green-yellow color (“puke yellow”) doesn’t work for me — I’d be a lot more attracted to the cover if it were a brighter, cheerier yellow.

I’ll leave the rest for our dependable commenters.
