The stunts in general were ok here, even though mostly old, they do take a certain level of skill to execute.
I do think you need some good advice on your editing though man. I might not be the guy for it, but i'll give you some pointers.
As mugetsu said, keep it clean. Unless you understand the effects your using (including pan/crop) just don't use them. A video with zero effects but good cam angles can still be a masterpiece, don't feel as if you have to apply effects on every corner of your video. Your cam angles here are actually pretty solid, keep them smooth and make sure you show the stunt and you can't go wrong.
Lower your flash transparency, as far down as 15% if need be, your flashes at the moment get in the way of the flow of the video. You don't watch a play at the theatre and whilst the characters are speaking they close the curtains for 5 seconds and open it back up? Keep the flow and you'll keep the good vibe.
Apart from that you're doing ok, keep practicing and work on toning down your effects so that they accompany the video, not overrun it. Good luck dude
