Nice but I think you overdid it way too much on the editing of the video. Keep up the good work and you'll be great in a few months time!
Also, I'd advice you not to learn from Showoff with cards. The flipback was done incorrectly. The method you used feels very uncomfortable IMO and De'vo's original method is very easy and comfortable to use.
The best DVD out there for flourishes for beginners is definetely Xtreme Beginnerz. Ok... the name is a bit naff but it is definetely VERY GOOD and the teaching quality is amazing. Everything is broken down much better in it than Showoff with Cards. Also, in Showoff with cards, Rob Stiff isn't the best flourisher in the world and he's teaching them when he can't really do most of the stuff well.
