Parasyte fanart. This is technically incomplete from a few years back, but looking at it now it's gorgeous as-is and didn't deserve to languish in my files forever.
It's supposed to have somewhere around 16-20 colors but counters are showing 74. I can't be bothered to hunt them down so it'll just be that way I guess. | 
Great rendering, I can tell that the lower parts is a bit unfinished but glad you decided to post this rather than leaving it forever.
Dunno what color counter you're using, but our image spec tool only shows a reasonable 22 colors.
