I've tried to retopo a model I made with Sculptris a while ago. I've tried ZBrushs retopo tools and I've got it done quicker than my last try in Silo. I think the topology of the nose is wrong, also I'm sure I have to redo the ears at least. But since I'm not an expert, is the general flow ok? Comments welcome.

I can't answer the question as I am learning myself (useing 3dcoat) but it apprears nice and now I will watch as the people who know what they are about answer.

Not too bad.  A perfectionist will have a loop going around the eyes.  The outer part of the eyelid has a star (a.k.a. pole) vertex.
