Please get a belt immediately. Your back angle relative to the ground is super flat. You should figure out how to get your torso more vertical and use your quads in the lift. With a back angle like that your DLs are like stiff legged DLs, and 295x5 SLDL is silly high if you're squat is 212.5x5. Take some videos from other angles that allow your shins, feet, and the bar to be visible at the start of the lift and post a form check to the SSC Q&A.
