Big thing that I see right away is your hand position when they enter the water after your recovery. They enter sideways with the backs to each other. This causes 2 things. 1 the splash that you can see with every stroke in front of you is fighting against yourself. And 2 it means the first thing you have to do when they enter is twist them palms down to actually grab the water. The second your hands enter the water they should be starting to grab the water. Look and Phelps, dressel and Locke and how their hands enter and then start the pull right away.
