You’re saying people should only give appreciative comments?
No… like I said… “Could there be anything done to make it better? Sure!”
Constructive critisim is half the reason to post your work to your peers… praise alone doesn’t help you improve your skills. But constructive critisim doesn’t have to be harsh. Again… I was just referencing some of the harsher comments, that to me just seemed to come out of nowhere like a sledgehammer. Although he seemed to take it all in stride.
I could give some constructive crit. to any of your work… again… anything can be improved… because it always helps to have the opinons of other sets of eyes. But I sure wouldn’t give it in a way that cut your work to pieces… I would just throw out a few things I see that personally I think might make the image a little better. btw… your stuff ROCKS!
Wish I was able to work on those type of jobs and get paid for it!! 
But like YOU said… it’s “referencing” human anatomy. That doesn’t mean it’s copying perfect human porportions or whatever. Too me… looks like a greek god. God to me screams exageration… therefore personally I don’t have any criteques on the anatomy, because in my opinion… they could be even MORE exagerated and out of “human” porportion and I wouldn’t have a comment on it. Thus that is MY comment on the anatomy.
Others may (and have) pointed to certain areas like the forarms and throw in their two cents about what might be “wrong” about it and how to improve it… that’s all great.
Now maybe the rendering, background, lighting, camera angle, material, etc… I would give some constructive critisism, but I don’t think that was the purpose of his work… it was a modeling exercise… pure and simple.
Just my .02…
