I don't like it. I never did like grunge walls at all. And your text's theme isn't similar to the wall's theme. Keep trying.
Not feeling the gray pic, I would keep the regular pic, and text and get rid of the background and the white pic. This would look nice with a simple background.
I agree with Courtking, I don't like the gray picture but the rest of the wall looks nice. I like the idea of him being a Floor General and it looks great. Nice Job and good luck with your graphic battle!
I'm not terribly fond of this wall either. The background is ugly, and the coloring of it is horrific. It would have been better without the grey picture if it was just one pic. I don't know if I like the font you used either. I would rate this a 6/10.
