PewDiePie mentioned TACO’s Direct Teaching! by TACO 1 times

Finally after I don't know 300 days of drawing, I picked up an art book. I should have done this ages ago. So I picked up a couple art books, some more technical than others but I really enjoyed this one TACO because I enjoyed the style of it. Obviously everyone has different preferences I think if you were to be a professional artist you probably want to pick like a human anatomy book and really study it.
