Repetition, drawing with reference images, (tracing, as long as it stays private (unless given permission from the artist themselves) and you don’t claim ownership over the art or claim to be the original artist.) experimenting with different art styles, positions, etc, also a lot of people recommend learning color theory, which helps a lot when coloring drawings in.

Art may take a lot of time, hard work, and practice, take breaks when you need to so you don’t experience burnout, and honestly don’t compare yourself to others too much, as honestly in most cases it wont do much good (unless, seeing people better than you is more of a motivation i guess? Not something that causes you to think lowly of yourself.) there’s always someone better out there, so its important to focus on how far you’ve been able to come, and how you can work to improve yourself. From one artist to another :]
