Jane Goodall walkthrough

I get asked for these a lot and as i'm re doing my web page they need to go somewhere so i'll pop them in my walkthrough page for now. In this piece i wanted to achieve a suitable flesh render without using a lot of circulism but i mostly get asked about white hair. there are many ways and this was just an experimental drawing for my then new pencil erasers. I wished to understand how i could use them. I made a promise to get the Goodall one up as soon as possible .. hope it helps
