only thing that needs changing is the subtext, I really don't thin it looks good. Make it in caps I think that would look better, possibly change the font.
Coloring looks like crap. I don't like the grunge either. Subtext is off. The render is just a picture with tape on it so it's not that hard to do. Sorry man not feelin it.
WELL I THINK IT LOOKS GOOD , your improving all the time with your work and its only gonna get better....only thing i would do is make another version with another color theme..besides that keep up the good work
