The technique is a bit off.. incorrect form. The artistic part is very well performed. Just for average players, you can learn quite good. Back view misses some of the hands gesture. Need front mirror view to see complete form. Good luck to you.
I think a music with a slower tempo would be better. The Form was performed in 7.42 minutes which was rather slow (not saying that it's wrong) but it did not synch well with the tempo of the music. Or else, it would be better to perform it faster....in about 5 to 6 minutes. I also think it's better not to use that "voice" if you want to have music. If the video is meant to be a demonstration for students, then remove the music....but please, get a better Chinese speaker. The "Chinese" tone does not sound like it's from a native speaker.
