Hey Grimber. You did a great job with the fire. The animation is very good as well. I think the only thing that might help is if you 'anchor' the base of the fire and use a twist, warp, wave type filter to rotate around the base in addition to oscillating the flame heights -right now the fire seems to have horizontal movement. I whipped up a quick example here at work during my break to show what I mean. It's not perfect as the top of the flame should move horizontally and I exaggerated the side to side movement but best I could do in a minute (wouldn't do to have the boss think I draw during work ).
