Not bad for a first.
Some constructive criticism.
1. Use registered FRAPS and turn on no sync so clips wont be recorded laggy.
2. A lot of old/sloppy stunts. If you land a stunt and it looks sloppy try it again until it is clean looking.
3. Editing could be better. Spend a lot of time on the editing.
4. Destroys naval grind is very very suspicious he starts to fall at SF bridge then suddenly shoots forward onto naval so Im gonna call that modded without a doubt.
