Very well done, maybe it was a little bit too long, I think 3-4 minutes would be perfect. You could/should cut out some parts where you get on your knees (not all, when you explain it and then show it, then not) or when you stand up. Also a very little detail: At the beginning the "learn 2 freestyle" was nice, but then I personally would do "ATW" and "Around the World" together; you save time and it looks better. :-*
Finally, either put your iPhone ear-phones in your ear, or let them completely away, I hated them hanging out there during the whole video. ;)
The rest was good so I don't need to mention what was good because you don't need to change. (in my opinion)
Note that I only want to try to tell you what I would do differently, to improve your next videos, because I like the idea. Most of the other tutorials only show the trick, but no explanation. So keep it up Macca!
Which trick are you going to do next? Htw? Tb? Crossover? ...?
