Squat:
Cut your depth off a little bit, you're going to tweak your groin down the road when the weight gets heavier by going so deep.
Knees are okay. There's not a lot of buttwink. Not enough hip drive. Your stance would be better if it was a little narrower - you'd like to have your heels under your ass cheeks at the bottom. Why are you starting your descent so slowly? Get your air, squat down then back up.
Power clean looks very good. Now put some more weight on the bar and see how it looks then.
