If you have them in your city I would advice to look for Andrew Loomis books. He explains like a God, really simple and useful. For books like "fun with pencil".
P.S. I'm self-taught too:)

Thank you, that is a wonderful resource! I found them all free at alexhays.com . You can read or download for free there. Awesome! Thanks again!

You're most welcome:) I prefer paper editions, I love to put marks in study books:)
