The author says:
This is for the first book in my YA urban fantasy series. I’m trying to go for a more urban fantasy/paranormal feel than the current cover. It’s set in the city and follows a teenage girl who has the power to control water and who is being chased by a Demon (she finds out later in the series that she’s an angel). It’s pretty comparable to the Mortal Instruments in tone and content.
Having read the description, I can therefore make the connection that what I’m seeing around her is water. However, for people who see the cover before they read the description, 98% of them will wonder if that’s some sort of bio-luminescent ectoplasm… and won’t click through to find out if they’re right. Confusion does not equal interest.
I think you’re probably heading in the right direction overall, but you’re not there yet. The model pose isn’t dynamic or active, the water doesn’t looks like water (as mentioned), the title font is a terribly dull Times-New-Roman-esque filler font (there’s only so much that filters and ornamentation can do to make a fundamentally boring font less boring), and the color scheme doesn’t look planned so much as discovered.
If I were hired to make a cover from this concept, I’d use stock photos of actual water that come up from the bottom as if the waves are magnetically attracted to her hands, find a font with just a titch of antique feel for the title (and extend it from side to side), and use the actual Mortal Instruments covers as a model for overlaying a consistent color scheme.
(Apropos of nothing: Chrome’s built-in spellchecker doesn’t know the word “ectoplasm,” but is just fine with “titch.”)
