335 is pretty good. Some work is needed though.
I'll repost Rip's recent comments:
Is my back angle too high?
In brief, you need to lean over more. Your back angle does not change at all from lockout to the bottom and back again. Knees out, nipples down, ass back.
This video is terrible for assessing your form for several reasons, but one of which is that the plates obscure you through most of the movement. We can't see what your back is doing. I suspect that you're getting floppy towards the bottom, which combined with your vertical torso, is contributing to the knee slide you've got going on.
You're looking in that mirror, stop doing that. Turn around and use the outside hooks if you can. Look at the floor.
