It was just a test on Mental ray with the head of Steve B (a wip version of the head), in the first page.
Man your Clayton sculpt is super expressive. Well done! 
Thanks Craigz !
Impressive work ! really nice sculpting details , bring us more breakdown for the skin material and i think it will be more fantastic if the eye ball has hdri reflections 
Sorry, for the delay…
For the breakdown, this is the same process of this great tutorial, “Eat3D_portrait production” :

it was fun to me to see your portrait in the icons, as i had done the same some time ago i immediately recognized him. very well done portrait. i think, you put the eyeballs a tad to far forward, as you need to imagine around them the glassy sphere that is bulged outwards to the front…anyway, wonderful portrait 
Thanks !
Yes ! it has been drawn from “Human Photo References 3DSK”. I asked me if somebody would recognize this model.
For the eyes, you have probably right, thanks.I’ll be more careful with that for the next
ps: I like your work by the way.
Edit: I added the turn (the timelapse is in the previous post).
