I'm slow...
Anyway this is how retopolgey works for those who don't know how and all, at least this is the way that I'm working on it. Left you see the sculptris model, in the middle the retopolegy over the sculpt and at the right only the unfinished retopolegy model.
The sculptris model is not useful for animating because of the messy topolegy so that’s why you need a retopolegy of that model.
I'll move this to scraps once I post another update of this.


This tutorial is rather useful for this kind of stuff, it's also rather short: http://www.youtube.com/watch?v=icqPZnD_3lA&feature=channel_video_title
