Hey friend! Sorry for not being able to reply within the same day but you know how life be Anyway, moving onto the whole reason why you posted on this thread…
So I’m going to start by analyzing what you wanted your covers to portray. When I saw these covers, my mind initially went to Dark Matter by Blake Crouch. They have a very similar feel and style to them.
However… that is a bad thing considering that Dark Matter is a science-fiction thriller and you want your novels to represent fantasy. (To be honest, when I saw your book covers, I initially thought that they were thrillers. Especially the cover for the first cover. I thought that was something to do with spies, detectives, etc. So we’re really far off on the marketing here.)
As for the feelings that you wanted the cover to envoke, you actually did pretty well. For the first cover, you really hit the nail on the head for excitement and intrigue. I had more of a tense, time is running out kind of feeling for the second cover, mixed with a little intrigue. I think your newer cover is the better out of the two, but again. Since the covers aren’t portraying fantasy, that doesn’t really matter.
First and foremost, you want your covers to portray your designated genre. And trust me when I say that this is SUPER important. You should see the book reviews on books whose covers or blurbs don’t portray the book the way that it is. (If you want to see how poorly it gets taken, feel free to google reviews/rants about Black Heart by Nicole Castroman or Project Cain by Geoffrey Girard.) So I’m going to help you focus on some elements of fantasy covers that I think you could draw inspiration from based on elements already on your covers!
(The last one looks like a prototype but it still has some really good fantasy themes going on in it so I included it.)
(As for colors, you really need to be selective on which ones you want. As you can see, fantasy leans a little bit towards more jewel/dark tone, solid colors. But something like that is up to you.)
