First of all, I am a newbie and this is my first day, this is why you see a lot of errors.
I also have lots of questions!
First question: is best to practice gesture and faces separately (one month gesture and another face) or together?
I am trying to decrease the amount of stiffness that my drawing show. With gesture I struggle with anatomy and detail (for me is easier a two-minute pose than a ten minute one.) With faces, I distort the expression one way or the other.
For faces, I don't know what I should capture with the quick sketches. I particularly struggle to draw people who smile with their mouths and teeth open.
Also, any good resources, exercises and books on said arguments are welcomed.
