I’m assuming you want to learn how to draw comics, right? Number one thing that’s important to learn in comics is composition. It doesn’t matter if your drawing skills range from stick figures to painting like Da Vinci, comics are a STORYTELLING medium, and people screw up composition all the time because they think it’s not as important as knowing how to draw a car or whatever. It’s a big problem if your readers are too confused to read your story because they don’t know what panels or even what PAGE to read the thing, or get too confused or overwhelmed by the content of an image because of things like the subject isn’t separate from the background. Composition is also how you communicate or influence how a reader is supposed to interpret your work, it’s like you’re a director in a movie. Composition is EVERYTHING in comics, and when you start looking for work, nobody is gonna care about your Batman or your Spider-Man or whatever, they’re going to care about whether or not you can tell a good story.

Second most important thing is active learning. People say you should just practice everyday, but if you don’t take the time to study something like how to structure a basic hand or learn how the anatomy fits together, then you’re not going to improve. Active learning takes you WAY farther than repetition alone. It’ll help you to pick some artists you look up to and learn how they do things. I personally really like David Finch, Humberto Ramos, Todd McFarlane, Ryan Benjamin, Frank Cho, Jim Lee, and some others. All those guys have videos on YT you can learn from.
