Here's a set of photos featuring an incredibly awesome female Commander Shepard cosplayer as what she calls "Biotic God." The cosplayer's name is Crystal Graziano, and she explains how she made the badass costume:
I made the suit of armor mostly out of foam, but the chest piece I sculpted and cast in urethane rubber. I made the bodysuit from a custom printed lycra with a design I lifted from a render.
So... what do you think!?
