Disposable Soldier: Cover Sheet

This is the cover sheet for my manga. It's one of those pictures where the artist draws the characters it a situation or whatnot, but it doesn't actually pertain that much to the storyline.

Note: All of my manga is hand-drawn, no computer altering or anything like that, so characters won't be proportioned exactly the same in every frame. I don't have any computer programs to do that, and it takes forever to make it perfect by hand. Anyway, contructive criticism is appreciated.
