1. There are tons of better options on how to do a quick transfer from slow and idle to hardcore drifting to DnB then go "Surprise motherf***er". Besides, you could see that coming a mile off, the slow bit was overstretched.
2. Sounds... well, try editing them to suit your needs, not just rip them out of a video and stick them to lfs footage.
3. Did the movie have an ending? If yes, why did you cut to black way before we got to that part?
4. Stock sounds of LFS + outsourced sounds. Pick one of those, stick to it.
5. Camerawork... well you pointed it at the car most of the time, so I guess there was some. Doesn't mean it was creative or good. Work on trying to show off the action your filming from the most dramatic angles, not just show it.
