Required reading before posting - particularly for the DL.
SQ: Looking at the 140, toe turnout seems a bit excessive and depth isn't always quite there. I would also let your knees travel a bit further forward on the descent, you are a bit too straight shinned.
DL: Angle is terrible here. You should post a video pulling from the floor normally. Since you *can* extend your back here in rep 1, you can almost certainly do it when pulling from the floor at *some* weight. It may just be form is falling apart at higher weights.
