Honestly, I would give the video two different scores.
Magic peformed (from both a technical and performance standpoint): 5
Video quality and creativity: 3
You mention it being a scene on a promo DVD. To me, that has a professional ring to it, and yet the video quality is quite low (resolution, FPS, etc...). In addition, you are in jeans and a t-shirt.
If you are having fun experimenting with video editing/filming etc... and want to showcase your magic for friends and family, then it is quite good. No problems. However, a Promo DVD? If you are meaning to submit it to business etc... for future employment purposes, than very much low quality.
On a more technical side, you seem to be quite comfortable with your sleights, but some of the shots could have been done better (some of your DLs seemed quite forced and *prepared* so to speak). This is a movie though, so there is no reason why you can't go back and re-shoot the scene and make it flawless.
You are on the right track, and you have some talent in your sleight of hand, so keep working on it. But as for the video, try PMing people like Alan Hagan, Kevin Lo, Tony Chang, etc... for some advice on filming/ editing/ software/ cameras etc... because a lot is needed for a *promo DVD*.
Hope this helps and I wish you good luck.
