Your deadlifts aren't bad. I recommend some shoes and especially some long socks. You are not keeping the bar on your legs right now. Socks will help. Also, do the steps in the sticky at the top. The bar is a little in front of your midfoot. When you are in the correct position, the bar will be closer to your shins and your hips will be a little higher. Those looked really light. If you cannot make 10 pound jumps as you approach 335 again, then make five pound jumps. I would bet that you will go right by 335 without a problem.
