TWITTER HAS NO CHILL
Baby brown bear.
So I see a lot of “use zbrush ref to draw from!” posts floating around tumblr.
NOW. Some of those zbrush sculpts are people’s sculptures, they are not sculpted from life and contain errors in anatomy/bad proportions. Don’t learn your anatomy from inaccurate sources, it’s a waste of time. Learn good anatomy first, then learn to stylize it. Start with realism and push outwards, not the other way around.
THAT said. 3dscanstore.com is a site dedicated to 3d scans of real people, example shown above. You can buy their models for about $50, load them up and use them. They have both the zbrush model and the decimated OBJ(which I think free programs like blender and sculptris will read) when you buy.
They also have fantastic 2d renders of their sculpts right there on the site if you just need quick ref.
