I think you are pushing too much with your right hand, and that is affecting also to your motion on the left one. you are lifting very good but i think you can lift a bit more, but the diabolos are coming too fast so you are forced not to lift so much with you left hand. I think just calm down a bit your right hand and it will be almost perfect.
Also the stick position of the right hand...is like pointing too much to the diabolos. It should be ideally perpendicular to the plane described by the diabolos, kind of more straight. Check dodson´s hand.
It´s funny that you included me in the thanks, I will remember it in half a year when you will be doing crazy 3D tricks and I will be trying to feed any sun, xD
I like the one hand bonus.
