It's pretty nice, but I'm not sure if the "lighter" part of the sig is supposed to be a result of a lightsource or if it's just a second color. The transition between dark and light is kinda bleh here. It's a good base which could use some working. :'D
Some areas are dull. not what split said about color, but just in general. though colors are pretty dull, he's right. also, <3dilated peoples.
