For some reason I'm reminded of Prince Zuko from Avatar: The last Airbender. Probably 'cause of all the really awesome fire effects in this piece, and the fact that it's coming from the character's hands and feet.
I find, you captured the African Wild Dog with perfection. When I look at this piece, I see a dog who is fearless, bold, talented, and brave. I would say, this shows a wild dogs true personality :3 Well done!
I was going to say at first the fire seemed a little dull, not as bright as you'd expect. Looking it over again, though, I think it would actually detract to have it any brighter. This piece comes together very well.
