I don't know if it's just me but I'm not feeling it. I don't like the pic you used but I like the lighting effects on it. The 2pac text could be better and instead of the letters being lowercased, you should capitalize them. Also, try and put a border on your sigs.
I think its your best. You could prob. add a little more detail to it, and add a effect to 2pac, and add a border. :happy0144:
