interesting looking bike ;-) whats your poly count ??

for poser, nice flames but a bit thin!! and all the flames on skull are from under chin ?? ok so I'm thinking blender but I'd add a scull cap to be a particle emitter

should be flames from exhaust too, a lazy soft one if bike is still and a hotter(thats gonna hurt) when its moving (like a gas axe)

 

did go watch the film again ;-) for me (at least) watching any film twice in the same decade (or two) lol just makes you find the bloopers but thats fun in its own right

nice work will look out for it
