Pretty good rendition.
My favorite character is Taokaka. This bastard is cool, but he's fucking difficult to play as.
Anyways, I'm here to talk about art, not Guilty Gear's cooler little brother. As far as accuracy goes, his mask feels too elongated; his mask is more circular, in reality. You did, however, do a decent job with making him feel ethereal and fluid, and I do like the kind of sketchy paint strokes. You did a pretty good job with shading, where it is on his mask and claw-things. Some little things, though are that he has a mixed look of looking like he's made of a shadow and cloth. I feel shadow, but some "cloth" texture would have made this piece great.
Overall, pretty good work.
