Nice video!, I think both shots look nice. One piece of advice though, Im in the proccess of changing from a 1 handed to a 2 HBH, and the first thing my pro told me is that I should fully extend my arms on contact...yours seem to be a bit flex when hitting the ball. Same thing with your forehand, maybe trying to change the contact point a little bit more in front of your body would help.
I though that quality of HS video would only be possible to get with a big and expensive video camera...you got it with a small digital one? Thats great!
