Take it back to the drawing board...
Even that one little motion of the guy putting his face in his hands is enough to show that you're an excellent artist.
But I wish you'd have somebody else write your stories and text, because you're clearly barely even literate. "Comming?" "Groupe?" I mean, come on. If English isn't your first language, I guess it's excusable, but really as a service to your beautiful artwork, you should let somebody who can read and write do the thinking part for you. It would add much more credibility.
And the line "It's easy to get on the battlefield--the hard part is getting off" is corny to a monstrous degree and barely makes sense. PLEASE get a partner.
