great tone and expression!
I thought your tone and volume was good. Although it's natural to focus on the things we did wrong (I certainly do this), there were many good things about your playing that you should be encouraged by. Musically it was excellent.
It looks like your hands are pretty big and your fingers are long - this is an advantage for the guitar, but I think particularly for your right hand it makes it a little harder for it to have the room it needs to hang naturally and be ready to touch the strings. I have found that from my right hand elbow down through my wrist and hand there is a continual curve with the wrist out as part of the curve and the back of the hand continuing into the fingertips finishing the curve. This results in a very relaxed wrist and with the wrist higher and out more might make room for your long fingers. Also, playing closer to the sound hole instead of closer to the bridge would make more room (obviously sometimes you want to play more by the bridge for effect).
The elbow/arm/wrist continual curve I describe is harder to achieve with the rest stroke (I have to deviate from it myself for rest stroke although this is probably an area where my technique needs to improve).
I would focus on keeping the right hand stroke movement in the fingers and hand as much as possible, and not in the wrist, forearm, or elbow. Wrist, forearm, elbow movement should not be part of the normal stroke (although sometimes for effect on certain notes forearm and wrist maybe), but their movement should be more incidental, maybe sometimes a byproduct of the stroke, but not a part of it. In general, the back of the hand, the wrist, the forearm, and the elbow should be pretty steady.
