@Souris , simply, just get started on creating something. Once you start, you can find new ways to get better at art.
One way to get better is developing your skill in the basics; that being anatomy, perspective, composition, and color theory.
Anatomy - look up references of people. Learn body-length relationships like the length of the arm compared to the leg and the body, etc. - The more tricks you have, the easier it is to draw. Keep practicing, no matter how long you draw.
Perspective - Learn about vanishing points, bird's eye view, worm's eye view, basic object composition, etc. Start drawing from real life objects and environments.
Composition - breaking down objects into simple shapes and understanding placement in panels to provide flow.
Color theory - experiment how some colors mix well with other colors.
What you should take from this is just start making stuff. The more you create, the better you will get. You can't see where you're going if you don't get started. For more on style and improvement:
