My 5/3/1 Style

Throwing up my current 5/3/1 training set up. I am transitioning from bodybuilding style to power lifting so at the moment all of my assistance is mainly hypertrophy based. I am amped up to completely change my focus to powerlifting because that is where my passion is and I feel like I have the greatest potential. I am just looking for opinions on how you all think my training set up looks.
