I like this concept, it reminds me a lot of the Star Wars Kotor games.

To make it more unique, I would suggest adding a big hoodie on top of the helmet that is an extension of atlas’s uniform – neck and chest – and some sort of boxing gloves that leaves the fingers open like in Street Fighter with Ryu and Ken. I'll feel like a champion and a fighter. You should also add more textures and it will be perfect.

It would be an instant purchase for me.
