Looks like a solid hit out to me, 20 sets, workout time around 45 minutes I would think, use that as a template and just fill in over time, with exercise variations and sets/reps variations, of course will depend on what you are trying to achieve:
Squat option – Back Squat/Front Squat/Bulgarian Single Leg Squat/Overhead Squat/Box Squat
Upper Pull – Bentover Row, DB Row, Chins, Upright Row, Pulldowns, Seated Row
Upper Push – Military Press, Bench Press, Incline Press, Bar or DB variations, Dips
I see you have done two pushing to one pulling I would go the other way since most people are anterior dominant to start with,
Sets/reps – 2 to 3 weeks high sets/low reps, then 2 to 3 weeks low sets high reps, there are a plethora of options available to you just change every 2 – 3 weeks, ash
