1.) For the front squat, I really don't see much wrong with your actual form. You need to ditch the plates under your heels, and start using either a flat bottomed show (Chuck Taylor's) or an Olympic weightlifting shoe (those can be pretty expensive). If you can't reach depth, you need to work on ankle mobility. I know it's just a form check, but you need to be lifting a little faster and heavier for us to really access your problems.
2.) Deadlift is about the same as the front squat. Honestly, you can't tell much because the weight is so light and you're purposely moving it so slow.
I seen you mentioned that the deadlift seemed heavy, but from the video that's definitely not the case. Maybe you're just not experienced in lifting heavy weight. Up the weight a little (don't go full on max weight), start pulling the bar with good speed, and your form will be easier to access. Also, ditch the slow negatives on the deadlift.
