Squat: not deep enough to parellel, not sitting back and engaging hips/hams/glutes, upper back doesnt look tight and arched. you do look confident under the bar though - which is good
deadlift: your entire back is out of shape, arch it the other way. dont look up, keep a neutral alignment. you do look like youre pushing through with your hips though - which is good
