Cool combo, like a realistic version of the American Idiot CD cover. Would like some slight hints of redness fading into the heart side, maybe even some slight green depicting the grenade from the other, but real nice details.
add a wash of color to the heart side, and please change the color of the shirt. A lot of designs are on whites, or lighter blues, and this design would look so much better on pretty much any color imaginable. If you kept this design on white, with no color, I would still rate it a 5, but when it would get printed I wouldn't buy it :(
About my design
Enjoy.
