I instantly knew this was based from a concept art, the way he poses. Well done!!
Could you do Nixxiom?
Hm, you're right.This looks pretty neat (glad to see you fixed the shoulder-pad issue), but I'm curious why you didn't just update the old model upload (the one you linked in your description, which you said this was an upgrade/remake of)? They are very similar, and it's not like you have to 'lose' the old one (you can make it a bundle).
