albinism
There's not a lot of information on his profile, so my comments are going to be on his design.
First of all, I like how "telling" his design is. The vibrant colors and unique clothing choice (the "claws"(?) on the ends of its sleeves, its coat which seems to double as a one-piece, the very long stocking-like boots, etc) seem to scream that this character is someone who is bold, eccentric, and very open about that. Coupled with the expressions and poses he often seems to have or be in, he also reads as a very smug guy to me (green is also a smug color). The traits I mentioned might not be your intention, but regardless I like how much character he has in the design alone, which is not easy to achieve.
Secondly, I like his face. It's very distinct, and it's hard to find humanoid characters with faces that aren't of the stereotypical, conventionally attractive model type (which isn't bad at all; such faces just don't stand out).
Unrelated to the character, but clicking through his gallery and seeing that the majority of the artworks of him were by you impressed me. You're great at drawing in multiple artstyles.
