Practice drawing basic shapes. Things like circles, rectangles, and triangles. Make big circles and shapes, as well as small ones. Then practice on specific body parts you want to be better at drawing, such as eyes, mouths, hair, arms, etc. Once you feel pretty confident with these basics, practice sketching the outline of some of your favorite characters with reference photos. (don’t trace over a picture, instead look at a picture, then try to draw it yourself. This helps you learn the anatomy of the character better as well as the art style.) hope this helps!
