Just finished up my contest design, a Deagle with a 70's space theme. I took inspiration from Ralph McQuarrie's Star Wars concept art as well as the graphic design style from/inspired by the 1970's.

At this point, I had loaded the gun into the game and noticed the beveling effect was looking was too subtle, so in the final design I increased the depth & size of the emboss. I also noticed my logo style was way too modern, so I redesigned the logos in favor of a more retro theme. I added a small bit of copper detail as well.
