The armor (in the two photos when you stand on a green grass background) looks great indeed, and I am making my new Uruk's armor in a similar version.
However, I feel that that the only thing that's missing in your kit, is a longer leather tunic, that will cover the area from the waist to your knees.
In my opinion, when the upper side of your pants is visible, it makes the entire kit look too modern.
Thus, if you add a longer tunic, (leather or cloth) it will make it look more medieval-based.
Take a look at Blozbarz's photo that I took in 2017, to understand what I mean:
Good luck,
