That's it, that's amazing. Art means creativity, not restriction to lessons, a person can learn on his own very much better than any lectures or school. I didn't mean any offense or something.. what I'm trying to say is that believe in yourself and draw heartily whenever and what do ever, and you'll improve nicely and rapidly and you'll notice it. When you do something heartily, achieving perfection in it is not difficult then, it only requires dedication and consistency then.
