Hey man!
Amazing work indeed, love the style and the details!
I have a few suggestions but disregard them if you haven’t done them yet:
-I think the body pose could support the face expression more. I think the glazed expression does work and is great, kinda gives him that “crazy or knows something we don’t” expression. Maybe some asymmetry could help.
-The pose from the front I really like, but the side view not so much. My suggestion would make him walking, weary and slowly, like he’s going somewhere that’s beyond “our world”, always straight ahead. I think that would support more his expression.
These are just my opinion, not things I think are wrong, ignore them at will :). Again marvelous piece!
cheers!!
