Gnomon is doing a really great set of online classes coming up (each ranging from 2-3 hours, total of 16 different classes from character design to 3d environments). Some really great artists will be teaching them too, like Feng Zhu and Craig Mullins and Sze Jones. Really worth checking out.

Yup, I know about that, thanks, Ivory Oasis.

One more info for those who like to draw 2D painting vehicle or such: Scott Robertson will be there too!
