I've completed lesson 1 and 2 of drawabox and the 250 box challenge. However, rather than continuing (for now) I think I'd rather learn (some) figure drawing first. Should I do the Learning How to Draw course first? And/or which aspects of it are not covered by drawabox, and which should be known prior to starting the figure drawing class? Or can/should I dive right into the Figure Drawing Fundamentals? Or continue on drawabox and finish at least lesson 3 first?
