A Mortarheadd mecha from FSS (Five Star Stories) manga by Mamoru Nagano. The designs of these things are unusual, but very cool. This particular one had clear resin for the armor parts. It's supposed to be transparent pink, and I had a hell of a time finding some paint that would work. I eventually went with some paint made for r/c car bodies, which didn't stick very well to the resin, but eventually I got it to work. It ended up looking pretty nice if I do say so myself.
