I am working on a book series called "Specials", about super heroes versus Demons and other demonic antagonists. While I do not require are for the other books yet or the other art in this book, this project only requires Cover Art for the first book.
The cover would require art of the main characters:
Kano, a 21 year old male, who is a moderate build of a man with brown hair and has normal dark blue shirt and grey pants.
John, a 23 year old male, and a friend of Kano, and is slightly bigger in his figure, with his hands shape shifting into weapons and is blonde. With a torn red shirt and jeans.
Riven, the third male of the group, he is a demon in a human's body, but is with the other heroes on the cover because he is one of the main heroes, the skin of the body is pale white, the hair is black with a grey stripe in the hair. He wears a grey hoodie and black pants and his hands hold fireballs.
Susie a 22 year old and blonde, the female of the group and she wears dark clothes, and levitates on the cover shooting lasers at the last character on the cover.
Satan, the main villain of the book would be on the other side of the cover. His face encased in a Metal helmet, with two large horns bursting through the metal, with two eye holes scratched open with blood around the eyes from when he clawed it open so long ago, and same with the mouth of the devil, it being broken to show yellow and rotting teeth. Down from the head, the skin of Satan is dark red, and his throat is sliced open from him trying to kill himself. But the blood is dried. He is starved and his bones are covered by a thin layer of skin, exposing his ribs, while many of his bones puncture his skin and protrude like thorns, large and small bursting through his flesh, while he has a trident named the "God Killer". With Latin on the handle reading "Laudate Sancti Una Est Mors Est".
The back drop being a portal to the Hell Dimension with three suns, the closest sun having the star of the pentagram burned on it, the middle star having the Anti-christ symbol, whereas the 3rd and furthest sun is untouched. Two moons, one cracked apart, and the second being fine.
This would be the cover with the very simple title of Specials.
