I like the concept very much. I'm a little troubled by the animals' original identities getting a little too lost by the fire, it's hard to tell what kind of animals they are in the end.

looks a little squished

Perhaps the rock should be semi-melting on the physical contact zones, another realism mark is never too much.

Very nice effect, good overall fire.

Thanks you, MossyB.

if the flames were more "wind-swept", it may be better.
need to saturated more to bring out the colors

Would have been great if you had shown the scorched, blackened & blistered flesh on the hand.

great idea CMYK46 I didnt think in that. but if you really think, there are not fire animals. so, this is not suposed to burn. so is safe to have it in your hand.

To me, the horse seems more like it's trying to escape the fire rather than being on fire as required by the theme.
