I'm not familiar with Nijushiho which may or may not be an advantage. All I could look at was the general impression and the basics. Overall, I'd say very well done. The single exception would be the side kicks. All the other moves are much as we would do them. We usually complete the side kick by bringing it back more. If that is not what you are trying to do, oh well, the rest looks great and I was just trying to look at it in a helpful way.
Unsu was a winner. I'd give anything to be able to do a kata like that. Same for Kitte, which also had better kicks than Nijushiho.
Awesome. That is what kata should look like.
The older I get, the better I was!
