Kevin,
Just got the videos and without giving you too much to work on we are going to start with your feet.
Next time you go to do a barbell movement for the lower body (squat/DL) do it shoeless and focus on rooting.

This will help immensely with your movement patterns.
For the deadlift bring your feet a little wider for the sumo pull that you are doing and try to keep your hips higher as well.

Add some rooting to the front squat as well which all things considered looked pretty good.
The TGU looked good as well, keep focusing on staying balanced and moving under control. That is why we start with the shoe.
