Nice job! V1 is the best... It doesn't really look right in B&W. But the guy in it looks a bit drunk. O.o But I like the logo hiding back there.
yeah it doesn't look as nice in black n' white. (The guy in it is Ronaldinho, one of the best football players, if not the best) :D
The color one aaaaaaaaaaall the way! The grayscale one is extremely bland...the explosion effect doesn't work too well when it's all in monochrome :/
The color one wins. Anyway, it's way too busy. Everything is all over the place. Lose the text, lol, it's extremely slapped on and bland to the sig. Nice try, though I know I've seen better from you.
