I think you’re getting closer, at least in the elements you chose. Here’s where I would concentrate my efforts:

• The ginger background, while pretty, doesn’t add anything except filing space.  I’d darken it enough to really contrast with the running figure.
• Your description mentions “sacred religious manuscripts,” and with the definite Da Vinci Code vibe here, one would expect something Latinate, not hieratic Egyptian.  Better change either the image or your description.
• In fact, I’d overlay the hieratic text lightly across the whole dark area, like so (five-minute version):

It needs a lot more work, obviously, but that’s the direction I’d go.

All Sophia wants is to leave work and see her favourite artist in concert. She meets him: Josh. He’s friendly and dreamy and they click. But before Sophia and Josh know what’s happening, their champagne is drugged and they wake up in a fashion museum. At least, it used to be. The museum is dark and unattended. The two of them are dressed in strange costumes, as are the mannequins and dress forms. Exhibits display creepy designs, unnatural taxidermy, random boxes and step ladders, putrid food in the employee lounge… No one’s coming back. They meet the other people in the museum. No one knows how they got there, and with no outside doors or windows, no one knows how to get home. The phones are cut, but surveillance is running. Tempers flare as food runs out. If they don’t kill each other, the museum will.

I honestly think you’re getting farther away. The text is hard to read, and the museum isn’t comprehensible as such without a good long look. And “warm gray” really doesn’t read as “suspense.”

Here’s what I think you need to do:

• Identify a half-dozen novels that you would expect to be in the same shopping cart as yours.
• Examine the covers for those novels. Look for commonalities.  As yourself, “How does the reader of these novels know that these novels are meant for him/her?”  Is is bold type? High contrast? Backlit silhouettes? A color scheme dominated by one strong color?
• Use the visual cues you just gleaned to come up with your cover concept.

Magda stands in the moonlit cemetery waiting for the spell to work, for her lover to return. But what’s done can’t be undone, and Magda will learn she should have left him in the ground. When twins Avery and Chloe Parsons receive a cryptic letter and a sinister-looking book filled with illegible scrawls from their grandmother, they set out for Prague to check on her. Drawn to a cracked crystal ball in a curiosity shop, Chloe discovers it harbors the spirit of their grandmother, who tells them a horrific tale of lust, naïveté, betrayal, and… demons. Armed with a book of dark magick they can’t read and a cracked crystal ball, the twins must stop Magda’s resurrected lover before he releases an unstoppable force that will consume the human world.

Across continents and nearly a century, follow the adventures of three strong-willed women: one seduced by evil, one struggling to withstand the lure of power, and one trying to save her family—and the world.

Nathan says:

I have absolutely no criticisms of this. It’s professional, it points to the appropriate genre… It’s fine.

Anyone say anything different?

Sing and color along with Christmas carols dedicated to 16 beloved North American birds. From “Silent Flight” to “Mockin’ Around the Christmas Tree,” these birding carols are sure to put a smile on your face.

Nathan says:

NEEDS MORE CHRISTMAS.

Seriously — from the thumbnail, the Christmas vibe is entirely absent, and even at full size you don’t notice the holly berries unless you’re really looking. Put some bold greens and reds in the framing planets.

Also, it looks a little unbalanced, top to bottom.  I’m assuming that the illustration was done old-school, which means that the jay can’t easily be pushed lower on the page; if that’s the case, I’d suggest moving the subtitle to the space under the jay, with the bylines pushed even lower; then you can also enlarge the title.

An underground detective agency is assigned by the Mexico City’s police chief to find the murderer of her daughter and other five women. A hardboiled novel set in 1993’s Mexico. In line with the works of Dashiell Hammett. Also, the novel is written in spanish.

Nathan says:

I don’t think this cover concept nails what you want. For one thing, the image is confusing in thumbnail (I thought I was looking at a caricature of a bald man with a Fu Manchu mustache).  The full-sized image does convey murder, but it lacks any indication of “hardboiled.”

In my experience, hardboiled detective novels (at least, those not written by authors who are already such a strong brand that all they need is their names on the covers) usually show the detective on the cover, not the victim (or, in this case, one of the victims).
