There's lots of awesome models on DA and lots of great places on the web to find pose reference and stock! Here's a little list of some great places to check out for some quality pose reference stock:
is a group I founded that accepts submissions of stock photos that are useful for pose reference. To be considered, the model must be wearing form fitting clothing or nude. There are separate folders for nude stock. Watching this group will result in quality pose reference stock appearing in your inbox!
You are here.
highly recommended male model, contains non-nude male stock with some action, and couple (m/f) refs with no nudity.
has an MASSIVE gallery, many of the female models are nude and make great pose references! There are also some self portrait pose references in the bearded, wizard type variety.
Mostly male, mixed undies and nude. Some fem parts.
