Thank you! I say you're on the right track already; draw what you love!! It's the best and fastest way of getting better. I used to copy pictures of people and animated characters that I liked when I was younger, and I think I learned a lot from that. Use your pencil or fingers to measure distances to get proportions right if you copy a picture; copying or drawing from real life is one of the best ways to get better in my opinion. Observation, patience, and lots of drawing, that'd be my advice. Have fun!!
