Ok well i'm only learning about jumping right now. I wish I could help you alot but I really can't I can only tell you things that I have read and might notice.
Well first off your doing really good I like this its great.
Maybe its just me but your feet seem a little out there not sure about that though because like I said I don't do jumping i'm only learning because I want to do it but I can't at the moment.
Overall I think you look good and that's all I noticed.
