Quoting Elliot Lannon
It's really cool and i like the burning tree, but why are the walls flat? And why does he have a cape?
The walls are flat because this is a cross section of a trench, It is just a small section of the entire battlefield. Also it is a vignette, so it had to be relatively small. The guy has a cape because he was based after a character in a book that is a WWI soldier and he wears a cape made of tarpualin, so I thought it might look sort of cool.
