Squats: You at least want to get to parallel on these, if you dont know what that means it means that at the bottom of the squat you want your hips to be at the same hieght as your knees. Wide stance, a squat is just as much hips and glutes as it is quads.
Deadlift- Get that ass down more at the beginning and explode off your heels. Just like most lifts get a nice arch out of that back. One thing I noticed about your deadlift was it seemed like you straightened your legs first and then used your back for the rest of the movement, almost like you did it in two parts, straightened legs then bent your back. DONT DO THIS!!.
You want your deadlift to be a single explosive movement upwards, your back is remaining tight and arched as you simultaneoulsy push up with your legs. The bar should be moving in a line perpendicular with the ground.
