First of all it's great! On every aspect. I like the way you setup a multitrack video so to have a more complete final result. Regarding your vocals besides the fact that you have a very very good technique I miss the atmosphere. I need more depth, some clinging high frequencies and more sweetness. I believe it's a recording thing regarding the equipment being used and I wouldn't mention it if it was not jazz. I will try to find a video to explain it...
