Here's my 2 cents worth... I agree with the previous statements that... - There needs to be some stretching, streaking, or motion effects applied to the fire and smoke, but not alot and problably not so much applied to the fire. With that much fire it looks like you are trying to capture the exact momment of the explosion. In which case there hasn't been time for the fire and smoke to streak back that much yet. There is going to be more streaking of flying of debriese from the explosion then from the foward motion of the plane unless we are looking at the plane after it has been hit. If we are looking at the plane after it has been hit then there should be less fire and more smoke and the smoke should be billowing backwards in a trail. - Booleaning a rock(s) out of the wing is a good idea, but use small rocks to make small damge detials close to body of the plane. - Most defiitely add the smaller debrise that would accompany such an explosion. Also... The wings tend to blow off a plane in one piece unless they take a direct hit. There shouldn't be a top and bottom half that have separated for one wing. The smoke and fire materials are very nice but you need to apply more of them to give them more of a chaotic look and shape. Make the fire objects much smaller as well. An explosion like that is going to take quite a number of overlaping objects to make it look convincing. Oh, and move the fire foward and center it anound the engine, otherwise you really need to blow the entire plane it bits to justify an explosion of that magnitude. Very good start!
