Too much music changes
If you're going to keep up the pace in your movies, don't chance the music all the time and stop them in an instant. For me, that was very annoying. Maybe fade them away or use them a bit longer, because the continuous changing creates a very confusing atmosphere. Consider yourself watching an enormous fighting scene lasting 3:00 and music would change 8 times. You'd probably go with one or two bits.
Though the graphics very good sometimes and you're having it there. Just practice little bit and you'll be, err, over there ;)
