The squat is not terrible, but you're getting your hips too far back at the top and then letting your knees go a little forward at the bottom.
The deadlift suffers from a lack of thoracic extension -- you're not getting your chest up into a good position before you pull. It's not that you're not dropping your butt as much as it is that you're not raising your chest. Both the squat and the deadlift could use a better back extension.
