Livid space to give more concentration to the two men bloody conflict. Is it ready for submission or is it too much of white?

The wallpaper is so plain... looks like you slapped the characters on a plain white backround, text, and that odd looking border. First, I think you should try to add more, whether it is grunge or them lying on a street. I would never use the wallpaper how it is right now. The border-like thing should be removed, it doesn't look right. What kind of wallpapers have borders anyway. The text doesn't really match either... maybe you should shrink it and position it to the lower left of the wallpaper.

=/ the characters look a little too red..(for my taste) maybe..try moving the level thingy around a bit. I would go for a grunge/tech type background (as said by bromithia). Also, were you trying to go for the um..jagged border thingy? Maybe you could make it a little more jagged (=/ not sure if it would fit with a background)

Waaaaaay too much white. my sujestion is to add a bg (maybe the character is in the middle of a street or something). give it a scene where a viewer could try to figure out what happened. just a sujestion if you want to put a good deal of time into it.

I think you should add maybe stone brick walls, and a street and cement sidewalk =] like a alley

I suggest maybe just a plain road or side walk add some cracks texturing and get rid of the border.
