Liked some of your aiko aiko from some other vid. This one didn't make much sense to me. I sort of agreed with the You Tube comment post to the video.
One thing I noticed in your vids is that your right hand should have a little more lower arm motion to get the bravado up. Those riffs would lose a little of their mushiness is you moved your arm a little more instead of leaving it all to your wrist and fingers. Not a lot of arm motion, just a little, and things would get the punctuation a little more defined.
No, his right hand, the picking hand. A little arm motion will change the dynamic of his picking, bring some force (bravado) to bear, and the increased sustain of the notes will allow him to coordinate the left hand fingering a little better to the right hand picking. (remove the mushiness)
