16 bit?
I really have no idea what this is from, but it's certianly great to look at. True powerful artwork is something that anyone can appreciate no matter what the source material. It really does seem like you drew this entire thing simply from looking at that single sprite. The detail is wonderful in this. If I was a bit more familiar with it, I might have liked it more, but it's still great. It's nice to see a person like you who really experiments with different kinds of stuff.
I don't recall designs similar to this appearing in any of your other artworks. It's great how well you define the shading. It makes you realize how important shading is to a great drawing, even if the original is done in sprite form. I like how his eyes make him look so stupid. You certainly have a creative talent with this guy.
