It's a concept that I invented, this type of two-dimensional costume which appears Photoshopped into the location. It's a portmanteau of costume or cosplay and pixel.
Ridley's come out great, ever since you showed his progression a few months back. And the shadow effect makes him rather intimidating (and certainly does make him pop out against that wall.)
Thanks! Between the two sides of this thing, I've gotten "big" out of my system. I'm going to do something simple next, but possibly less human and more mechanical. Maybe.
Great work!
