Ragnarok, thanks for those suggestions. I was eventually going to get around to animating the head and nostril areas (like a small sneeze), but hadn't thought about what to do for the rest of the body.
Could you clarify about the stomach reflection, though? I'm not quite sure which part you're referring to (the way I've got the highlights from the fire, they're basically static until it starts to dissipate, at which point they semi-gradually disappear).
