I've filmed my deadlift, squat, and bench and had them reviewed. Little pointers here and there, but I prolly would benefit from having a trainer for a bit. My squat was problematic, which is why I switched to front squat variation - my upper back mobility wasn't allowing my wrists to go into proper position, and my hips weren't bending to get my butt to stick out correctly. My deadlift looks ok, but I'm getting lower back pain that comes and goes. Im having trouble differentiating between doms and back injury, and I might just be a hypercondriac. And then sometimes I get shoulder pain when I bench, like my shoulders bout to pop out. Not every time, but enough for me to think I need to fix something - maybe only go to 90 degrees, instead of to the chest.
