What Loomis books are you using? Fun With A Pencil teaches you so much even though it's such a simple book. It makes it easier to understand things if you start very basic, even if it hurts your ego. I learned so much from it and it made everything else easier to understand in other books. I'd really recommend it, I'm not even done with the book and I've learned a lot.
Vilppu videos are very informative too.
