But more to useful critiques: That left arm is just a little bit too long. The tail also seems to be going in odd direction, with respect to the cape fwoosh. The rest I can attribute to sketchiness, but those are the standouts. Judging by your theme last week, you're still putting your focus into expressions. And I can say that it's continuing to pay off. What we have here is an expression of pure anger, with all remnants of self-control long since obliterated. Something has been getting under his scales long enough, and the reckoning is here. This kobold will have blood tonight.
