ok the 1 pic border would be better on this one cuz the background is already very dark unlike ur current signature.
second.
the right part of the signature totally rocks, love the brush effect and the marks in the background.
BUT, the left part of the signature wich wasnt in the red part like above picture.
its just...hmm..his gun looks a bit low qualitiy but thats not ur fault. however the other left part(background) looks very plain indeed and almost looks like u have forgotten to fill it.
if the left part would be as great as the right. it would rock.
and the font/text is good very nice
i hope these comments help a bit
good job on it
