Hey Pav, I've got a few comments:
1. Your opener was a little unclean with cards getting stuck behind. It's worth it to do multiple takes to make sure that you get a perfect, clean block of cards sliding out of the deck.
2. With several of your moves the packets would often get a bit disheveled. They would start to come apart or otherwise cease to be perfectly together. Keeping packets clean makes the moves look many times better, so it's worth doing multiple takes for that, as well.
3. If you're right-handed, don't film from the left so much. It obscures some of the motions. Mix up your angles. Straight-on works, so does from slightly above, and from the right. Play with all of them.
4. While this is a matter of personal preference, I felt there were too many two-handed cuts in the video. I'm craving more variety. While the two-handed cuts you used looked good, they all begin to blend together when it's just cut after cut after cut.
5. Again, a personal preference, but I would like more uncut sequences. Having each single move be its own take and cutting to black in between upsets the pace of the video and can get boring.
I also agree with the above comments regarding your background / setting.
All in all, you have skill, I would just like to see it showcased a little differently.
All the best,
Vince
