Squats look pretty good to me
Seems like you're keeping the bar mostly over midfoot throughout the movement (at least more than I do), which kind of explodes my #leverages argument for why I have trouble doing it. Shockingly, it likely just means that I suck at squatting.
Kind of hard to fully see the RDLs, but I think your lumbar could be a little more set. Are you using straps? It might help if you did, since the weak point on these is pretty much always grip first.
