My bad I should’ve filmed it landscape*
These look pretty good. You just seem like you may be overthinking the reps a bit too much so there is some hesitation at the beginning of each rep. Note how your hips slightly drift backwards and your torso angle changes before you begin most of the reps. My only other critiques are that your elbows look too high (should be more parallel with your torso) and you’re looking straight down. I can’t tell what your grip is like to make any comments on that.
