Nice, but you should remove/change some of the dithering, notably on the forehead, and maybe on the legs.
Try to add a bit of yellow/brigther colors in that light too, that would look much more real.
Appart from that, really nice colors, the torch is very interesting and the tongue is wonderfully done.
I like the pattern of dithering and the colours combined but perhaps the fire might have some yellow in it?
I don't see the point in featuring the palette in the piece, at least not in this composition-killing way. Find a creative way to do it if you really want it ;) Nice colors anyway.
Good piece, could improve: mostly useless dithering; anatomy looks wrong in the arm; the flame and flame-lit areas don't read as highlights.
Also I think this would look way better without outlines.
perspective in hammer is wrong
interesting set of colors
That dithering
