I'm still wondering about your reference images. I remember you mentioned that you had a new camera. Do you make your own reference images from people you know?

It seems like I read that the original mesh will sometimes need to be retopoligized based on changes made in zbrush. I have not use zbrush so I'm not sure about that, but if it is true then it might make more sense to use the proxy.

What is it that you do not like about zbrush? Is it the gui? Is the gui in mudbox very different?
