Great job on the armour
I was going to mention the biceps but it they fit you fine, then no need to mess (unless you think you can taper them in at the bottom slightly?)
You might have to trim the prongs on top of the back plate to allow you to lift it up. You can also trim the neck line deeper if you want to bring the chest up a bit too. These are things I do for people who a bit shorter than the desired 5'10" height.
