Clone trooper sig

I got most of my renders from Planet Render...I've been trying to work on a few of my own...but I still suck at that o_O. Break it down and tell me how to improve guys =)

All of your sigs are low quality. The backrounds are kinda plain, so try using C4D's. But make sure to turn down the C4D's opacity and try using them on Screen or Lighten. Whichever. Your text needs work aswell. Try not to use such "fancy" or "hectic" fonts. Your sigs are also very flat. Make sure to give them some depths.

weellll you could always have fun smudging as well. The 2nd one is interesting though xD very creative
