1 & 2

The Morvyre (1) & Kaia (2)

Kaia essentially gets kidnapped by this creature called the Morvyre. He lures people into a forest to feed another monster that he basically chose to care for and keeps them in a cave deep in the forest. The monster then chooses who he wants next through their dreams. This is what starts the story.
ACTUALLY, I decided I just want a bust of Kaia on the front, kinda looking over her shoulder almost like the reference! So kinda facing 'us'.
So it would be 1 bust (front cover) and 2 half body on the back.
Kaia has light brown hair and hazel eyes.

Jace (3) & Rhiannon (4)

Jace is Kaia's older brother. When she goes missing, he decides to go find her. Jace and Kaia are my world's version of 'werewolves' but only Jace has the ability to transform. However, if he were to change in this forest, he wouldn't be in control so she's basically there to protect him. Rhiannon is a 'vampire' who rescued him. I think it would be cool to have her in her vampiric form haha
Jace has lengthy brown hair he usually keeps tied back and brown eyes. I know the refs show piercings but he has no piercings or anything. Rhiannon has long blonde hair and green eyes.

(5) My ideas for the spine are to either have both images (the back image on the right side and the front image on the left side) fade to a black color in the forest, or layers. The front image (1&2) being the top layer, trees as (5) being the middle layer, and the back image (3&4) being behind that. So you’d be able to slide the trees behind the front image. If that makes sense? And then just slide them all over. So there would be like 4 different layers at least. The main background image, then the back cover illustration, then the spine, then the front illustration. If that makes sense? You’re pretty good at making things adjustable for me, though!

(6) The flaps won’t have anything important. Just an extension of the background. :D

The background itself can really be just some woods. It doesn’t have to be super detailed or anything.

Below is my main cover that will go with the illustration to color match the woods and whatnot.
