I know, its looking like Nasuke's head. Thats true, he inspired me totally. I came back to Crysis and its inspired me too.
C&C please, and say what can i add. It may be simply. Maybe something like sign's on back or something.
Advanced Commando Urban Soldier must be something like.. hmmm Darth Vader's Stormtroopers?
They must be simply and scary.
C&C and suggestions will be pleased.

Haha lol. Very good
Add a visor and maybe some more details on the front, like the small indents on the lower portion. Experiment with shaps etc
Add some shadows
Make the plates join at the back somehow
Use gradient for the green
I think that's all

Put scratches on it and put some more detail in the lower jaw
