Mind explaining what's going on the background?
For once I actually do mind... But, I guess it can be described well as "blood and violence". Unless you are referring to the background, which are trees and a rock.
Anti-showing what is going on the background, pro-I don't have layers, how do I correct the lineart:

Also, instead of drawing for the ASC (I guess I won't enter this round), I drew horrible monster that does not enjoy wings belonging to other people, I guess. The scene is largely incorrect.

And the background is largely blue, because I was getting tired of drawing. I also need more browns.
As for the AU, well, I think this would be canon.

I will spare the details.
