Another difficult solid single color outfit, all the more difficult because it’s all-black.
I bit the bullet and used some tiny pixels at 512×512 resolution to provide outlining.
The gun was pretty cheaply done, since I didn’t bother changing the arm angle. It looks like he’s not holding the grip of what appears to be (maybe) a revolver. The way the arm/hand is angled, if he was holding the grip, the barrel should be pointing down.
