Pretty cool looking. Linework is very clean and the shading's done pretty well too. A couple things stand out though. First, the fire on the tail looks out of place amongst all the well-defined lines. It's blurry and nebulous. Yes, I know real fire is, but if you're drawing the cel-style with clear lines on everything else, the fire should be the same way methinks. Secondly, the tail comes out of her bum way too thin, and at a right angle. Tail=spine... it has to continue the line of the backbone to start with, then it can curve out to another direction. Lastly, the eye is looking directly at me, even though her face is looking almost directly sideways. I should never be seeing a symmetric eye from this angle... with the possible exception eyes belonging to fish. Figments of the imagination have anatomy too! :-) More nitpicky issues, the halo and the fire are both very red, so the light they cast should lend a red glow to nearby stuff. The lighting on her lower leg looks more like a flashlight, and the top of the head isn't getting any light at all from the halo.
