Hmm… Personally I don’t get the harsh criteques of a the anatomy of model of a guy who has a third eye in his forhead? 
This right there tells me that “human” anatomy is out the window. A lot of people seem to be comming down hard because it’s not this “pefect” human anatomy… and there is a BIG LIST of things wrong with it. A big list of anatomy problems of a guy who has a third eye in his forehead?
Hmm… also not to mention that it’s refrenced from a real life sculpture, which to me at a glance looks like he nailed it pretty darn good.
I am not familar with this sculpture… but looking at it, it appears to be some kind of greek god. To me, greek gods scream exaggerated features and such.
But that’s just me. 
So to me… there is a BIG LIST of reasons why the anatomy should NOT be perfectly human. And that this is one heck of a modeling job! Specially for a second piece of work in Zbrush. I couldn’t even touch anything like that quite yet. So Good job. Could there be anything done to make it even better? Sure! But you could say that about anything. But at some point you have to abondon your work and move onto something else. Personally I like to use the 5% rule… if what you are going to change/redo/remake/add/delete/etc… is going to change the final output less than 5%… stick a fork in it and be done with it and move on. Otherwise you will be tweaking it till the end of time.
But I also believe that as a society we have lost sight of the concept of dimenishing returns. But again… that’s just me. 
Now wether it belongs in the choice gallery or on the FP or not can be left up to debate, but that’s always going to be a matter of opinion. We are all going to see images that we feel belong in the choice gallery or FP that don’t make it, and vice versa.
Wish I was able to work on those type of jobs and get paid for it!!
