In 2013, 3Dtotal released a set of crowd-funded anatomy resources for artists everywhere. The figures were so popular, that they’re back with additional models to expand the collection. The new set includes male and female planar busts, a new book on head anatomy, and a seriously cool adaptable male figure. Check out the gallery below for more pics. If you’d like to help them fund the extended collection, check their Kickstarter, and help spread the word on social media.
