Upon second viewing... notice in the second half of your video when swimming away: the angle of your right hand when it exits the water. Compare to the angle of your left hand upon exit.
I like the alignment of the left hand better than the right.
It seems like you hold tension in your wrist throughout the stroke on your right side. It may be doing something funny underwater to get to that position as well. Relax that wrist, straighten it out, and you may find you can relax some tension in your shoulder too.
I have been working on not "grabbing" the water during the catch phase, and sometimes it's surprising how little finger and wrist energy it requires to keep the hand and wrist in proper alignment with the forearm. Instead of attacking a full- fingered piano chord, I try to imaging patting a big dog on the back with my fingers. Or in Star Wars terms, the more you tighten your grip, the more (water) will slip through your fingers.
