As a quick job, it's excellent. If you wanted quick tips to improve, then try adding more details in the texture at the back of the head and on the clothes. There's so much detail around the eyes that it feels like other parts of the image are empty. Otherwise, it's a good extrapolation of the reference into the 3rd dimension.
I didn't expect anyone but Jouste and the other game artists in my sketch group to see it...was more focusing on form for this practice session but I'll put more time into different areas next time.
I do agree about the clothes, should have extruded them a bit thinner on the collar there too.
I like the renders in your gallery, you use Maya? Max? Blender? I use Maya for base mesh before moving to zbrush normally, this time I went dynamesh all the way.
Thanks for the critique! *Jouste style virtual high five*
