Critique my form? (again...)

Hello all! I'm back again to get my form critiqued on these exercises , I'm sure that there is a lot to be fixed lol. I'm posting them in gif format so I hope that is alright. Looking back I probably should have worn a tighter top.

Underhand Pull Down (I have a hard time with these. I can never feel anything even when I use a heavier weight)
