Back looks pretty good. You would probably be able to set it even better if you weren't pushing the bar forward with your shins prior to every rep. This causes the bar to be out of contact with your legs for much of the rep and to swing back towards you. Remember, we like straight lines on the pull. Go up by five pounds next time. Get the bar over the middle of the foot, get very tight and drag it up your legs. On the whole, you deads look pretty good. Just need a little polish.
