Thanks for the recommendation.
I read "drawing the head and hands" by Andrew Loomis a few months ago but I din't fully grasp most of it at the time.
I'm definitely thinking of going back to reread it now that I have more of a grasp of some of the fundamentals.
Are there any of his other books you would recommend?
(Still just doing studies from photographs since I don't feel confident enough to study without reference at the moment. Tried giving them a bit more polish today)
