I liked this poster someone made and wanted to re-create something similar for the front.
Found the actual photo used so I figure it'll look pretty similar lol
Desatured, added diffuse and unsharp mask
Gradient map and levels
Sky background added and matching
Trying out a different sky and adding a character
Wanting to make the cover look like an old mystery paperback or book, not sure yet how to achieve the spine
or make that page underneath look more realistic. Might have to wait and make sure the front is finished so I can merge the layers on the front to manipulate them a little easier as far as that goes.
