I'm going to second "Drawing on the Right Side of the Brain". Has some amazing exercises that'll have you drawing in ways you didn't think you could.

I would go to like a half priced books and pick up any leonardo anatomy books, this is how I remember being taught to draw people at an early age.

@bitcoingraffiti how'd you learn?

I have a weird thing affinity for faces. I'd also be interested in a good book. Ideally something I can do daily.

I've heard of "Drawing from the Right Side of the Brain" being good. Are there any others you'd recommend (for drawing faces / people), fantasy is OK too
