Your depth is inconsistent on your squats and almost every rep looks a little different. Get just below parallel every time. Stay balanced over the middle of the foot.
Bench - pinch your shoulders back at the beginning and keep them there.
Cleans - get a wider grip, start with your hips higher, and, most importantly, touch the thigh every time.
You need to gain a good deal of weight. You will find this helps your lifting a lot.
