I know that you’re looking for book, and I might be going a bit against the grain here, but, there’s nothing that you can learn from book unless you observe people in real life.
I have always loved life drawning ahd to start off, it did look at some books… well, at least, up until my father caught me, and “kicked” me out of the house with a sketch book and a pencil in my hand, saying that life was outside and not in a book.
Sure, drawing from life it difficult, so I started out bit by bit, first I started from pictures, but I didn’t feel satisfied, because, they make your drawings look too “2 dimensional”. Then I moved on to sculptures, there’s nothing nicer that going to a museum and just get lost amongst the statues and paintings.
After that, when I started feeling a little bit more confident I started life drawing classes, because, nothing replaces a good life drawing teacher. Finally, I started going out and about, and drawing people moving around… This is really makes my heart pump, what a rush! Trying to capture people as they move around (especially , little children!!) might be frustrating but, sometimes you can really capture something special.
So, do the Anatomical lesson, it is a nice way to start and show your drawings to as many people as possible. At first, first your drawings will be a little shakey but, if you persist pretty soon an A0 piece of paper won’t be able to contain you :bounce:
