I like looks real imo those two spots under the helicopter are really bothering me, mebbe you could do something to the color of the fire to make it look more realistic its cool how it is but it kinda like iuno >< how to say, it looks real but like something about the color.
Correct me if I'm wrong but the only thing you did to improve the fire was to add the same effect around the piece some more :\
Haha, not 'horrible', but definitely not great. The fire is pretty bad. lol but the helos fit in with the lighting well.
