Special feeling to it, no doubt

 Interesting entry!  A few things I notice is that the monster does not seem to reflect any light from the lava at all, which makes it seem disjoint from the scene given that the only imaginable light source is from the lava.  A quick edit: img.removedfromgame.com/imgs/lavam.png

I also feel as if it could use a more complete rendering (more detail, and a touch-up of some rough areas, for example where the lava escapes from the monster's mouth -- which looks rather blocky right now.)  I like the idea of the contrasting pink and orange, but I think the pink is too saturated -- my edit above makes it more manageable.  In the current state the pink is so contrasting to all the other colors that one's eye is drawn directly to the monster's face, which (I think) still would need a bit more polish to be the absolute center of the piece.

You also had an extraneous color in there, which my edit gets rid of.  It's located on the monster's cheek facing us, and it looks identical to the color on the ramp that's brighter than it.

Nice job overall.
