Amazing work! Probably the most realistic character I have seen on here. The orchestration of detail is masterful. You gonna color him in? That would be something to see.
Damn, these are all really great. Super cool to see such a big mashup of realistic and silly characters and even environments which look great as well. Thanks for sharing!
the proportions are realistic. I think its a good base for sculpting, if you were not gonna sculpt, i'd say it needs more definition around the ankles and feet.
The ground material in the top picture looks really nice, but I don't necessarily think it fits if you're going for a Blizzard style environment. It's a little too realistic.
I thought what he meant was either "good lighting with generic cloud filter roughness" or "realistic/ logic wear and tear placement on a dull light setup".
Which max version are you using? "realistic" in 2014+ actually manages to SORT transparency! Not kidding ;) (right now the alpha seems to cut your body in the viewport)
Also remeber it is a concpet which likely dosnt have realistic lighting anyways. So if the concept can take artistic liberty you can and will have to as well.
