Not too shabby.
For deadlifts I would try to get your butt back more and get lower. You can watch Franco Columbu, one of the strongest bodybuilders ever, do it here:
It can be hard when you're tall like you are, but keep getting low and keep the butt back until you feel it turn into more of a full body movement and less of a lower back movement.
For the squats I would lighten up the weight. Focus on slowing down your decline a bit and try to get a bit lower. You want to be at least to parallel with the ground. You're a little above that right now. Concentrate on feeling the weight on the outsides of your feet and drive up through your heels and hips.
Good work thus far!
