You can learn a lot by......

Tracing.....A ton of great artists out there learned a ton by tracing comics they loved or from photos. Trace first so you can almost mindlessly break down how the artists did what they did, then draw it from reference, then draw it from memory. Might seem like a big commitment but it will help you memorize skills you'll be able to incorporate int your own style for the rest of your life. Just a tip. I DO NOT condone tracing work and passing it off as your own, but used properly it can be a fantastic learning tool. For all of you that struggle with drawing backgrounds, it's a great way to learn that skill as well. Find backgrounds you like in comics or just convert photos of scenes you like into black and white(or grayscale) and figure out how to indicate the various areas with a pencil. It's not cheating. In another post I'll outline how some artists base their entire style on tracing. All the best! IIId
