Looks good, just try some variations:
-Do rear delt work later. Start with presses & laterals. 3 or 4 sets of each, moderate to high reps, 45-60 seconds rest between sets.
-Try presses behind neck, they'll hit the lateral head better. Yes, they can be hard on the shoulder joints therefore use 2/3 ROM avoiding the bottom part, and keep the reps moderate to high.
-Use a Smith machine for presses. Without the balance issue you'll be better able to focus on the delts.
Try these two, for a few weeks or months each (not both at the same time):
-Supersetted presses behind neck + DB/cable laterals.
-Negatives on presses & laterals.
