that's a WIP, no doubt!
advices:
-fire should be painted with lighter yellow INSIDE and red outside (try to watch a real fire, hotter part is yellow and colder red)
-remove the metal bits BEFORE painting, or you may risk to ruin the paintjob removing them later
-i like legs colour, but it's a little too glossy... try a matt overcoat on them
hope my comment will be useful!
cheers =)
