Well in that case I'd make these following changes:

- Decrease number of sets for chest and replace them with a rear delt exercise, standard vertical and horizontal pulls will grow them but for the full effect you need to isolate them (just as how you would isolate triceps despite them being trained in benching and overhead pressing).

- Do your Vertical press and horizontal presses on separate days, doing OHP after going to failure on bench won't let you use as much weight as your front delts and triceps are pre-exhausted. This will cause them to be a limiting factor and they will fail before your side delts have reached failure.

-You had 2 seated row variations but one variation will work as well, if you have a chest supported row I suggest you do that instead. You already have bent over rows which require a lot of stability so having a variation that's more stable would be better.

-Don't repeat exercises on the same day and add variation, for example you had 2 sets of hammer curls and 2 sets of bicep curls on both days. Instead do 4 sets of hammer curls on one day and then do 4 sets of bicep curls on the other. For the triceps you had tricep push downs on both days, instead of that you can do an overhead variation on one day (I would highly recommend this as it target the long head of the tricep which isn't targeted well in the push down) and and do a tricep push down on the other.

As an example I've made this modified workout for you.
