I'm not a big fan of straps for your work set, especially when your work set is only 295 lbs. At this stage in the game, you should be using the deadlift as a grip exercise as well. Do you have exceptionally tiny hands?
That said, and recognizing there are things we can't see from this angle, these aren't bad pulls. Get a little more set before you pull (squeeze chest up!). Also on subsequent reps, the bar looks to be moving forward around your knees rather than up in a straight line. Check your position to make sure the bar is over mid-foot when you start the pull, not behind mid-foot.
