The parts are all appropriate to their instruments, I don't think as a player I'd have any complaints. Separate from the video I think it's not bad, although I could use more sense of direction within the piece. Since it's accompanying the film, I think it should tie a little more to the excitement of the scene. It felt too relaxed, not urgent enough. Think driving rhythms (hee hee, look a pun!) and more crash cymbals (oh look, another pun!!) or something to accentuate the intensity of the scene!
Good work, keep going.
