On your snatch it looks like you've got a bit of an early arm bend and you're not quite getting full extension. Also, I would stay try to keep your weight on your heels a little longer.
It looks like you're catching the weight out in front of you, but you're strong enough at that weight that you just muscle back into a position over the shoulders.
With the clean, are you releasing your hook grip on the turnover? That would be the biggest thing that my amateur eye sees; your turnover could be a little quicker.
Just my two pennies! Good lifting!
