Book Cover Makeover and Review!
This is my favorite book of all that I read for the challenge! The climatic scene takes place in an decades-long abandoned subway tunnel that has been iced over and coated with a moss-like substance. I found a subway tunnel on the internet, cropped and greened it up a bit.
The climactic scene takes place on a marble altar where there will be a human sacrifice. Back to the internet to search for a stone altar. Cropped it, gave it a bluish tint because the subway tunnel is covered in ice as well (it takes place in winter).
Then combined the two photos, added the apple, dagger and blood and voila!
