I like it
but i'd like to give some feedback.
- I'm not an expert nor can I draw good! So you don't have to take me serious.
1) the right foot. maybe point it the other way? and it's below the left foot. so it looks like the right leg is longer. I would make the right foot a little bit . uhm.. with a angle. you know? dunno in english,
2) less lines. try to make it more realistic? give him muscles etc.

3) he is standing a little bit strange imo.
my opinion about the guy.
1) I would give him a cooler hairstyle :P
2) armour in green is nice!
Good luck!
