Like others have mentioned, it's a good start but could use work. The text could be cleaner and you can even line it up with the barrel of the rifle or incorporate it into the gun more, rather than have it in a corner. The gun itself look ok if you like the simplistic cartoon style. If you want a more 3D or abstract, I could maybe mirror it or make it more realistic. Also, instead of a border all the way around the image, I found that a horizontal line above the top and bottom of the image looks much more professional like the signature in gamer4evere's sig. But hey, if you like the pic then keep it! There's no use listening to everyone else and end up with a piece of art that doesn't please the owner.
