Definitely gonna have to add to the notion of anatomy (for 2D and 3D artists, as I know of the sculpting one but seems designed for sculptors, as you’d expect), especially considering it’s vital for both 2D and 3D characters this would be invaluable. I’ve gone online and noticed most anatomy courses are really charging the big bucks so it’s a pretty difficult subject to break into, I think the CG Cookie crew could really do justice to an anatomy course
