I like it in green. You could make a blu one two and he would be captain of a diferent troop...or something.
Q: is the movable part of the helmet upside down? why? 
The upside down style of the visor makes tha helmet look like a kabutops helmet...(cant find a pic...the damn pokemon is keep coming up on googld search!
I kinda have connected these legs with blue...green is better with the brown indeed
---edit----
Better luck with ''samurai helmet'' search...
