It's good to see people so interested in drawing in 2D and in traditional media now that everything is going to digital & CGI/3D.
You're certainly a part of that. Congrats
Something you said disturbed me deeply, though. You said you took a class "Drawing on the Right Side of the Brain."... I assume that class was based on Betty Edwards' book?
I'm afraid her book has done at least as much damage to aspiring new artists as it has helped.
It's not really a book for people interested in learning how to draw; instead, it's a book that demonstrates that anyone can learn to render things much more accurately than they think they can. It does get your hopes up that if you stink at drawing, that one day you can learn to do it right.
HOWEVER.... it's damaging in that once you're through with the book, you have the sneaking suspicion that you haven't learned anything about drawing.... even if you religiously practice all the blind contour exercises and everything it suggests for weeks and months... and that suspicion is right! You haven't learned anything.
Understanding what you're drawing ultimately comes from the left hemisphere of your brain; all understanding does. Language comes from there as well. Recognition comes from the right brain. There's a difference.
Unless you understand what you're drawing--the construction, the way light works, the proportions--, you'll be doomed to try and copy everything with blind contours the rest of your drawing career. That's a huge handicap.
Just understand this if nothing else: You can't rely on your right brain to carry the entire load if you want to become a successful, fulfilled artist. Betty Edwards only gives you part of the story. Her book is meant to get the ball rolling--not to give you all the answers about drawing.
Hope this helps in some way; to get started on the left brain side a bit more, grab the Bridgman book or another like it. Study the simple constructions of the human form. That is understanding. Eventually you'll be able to combine that knowledge with the cognition and creativity of your right brain, and you'll be a whole artist!
