Are you working on paper or digitally?

The answer is really simple: practice, practice, practice, and perhaps enroll in a drawing course. And/or get some good books on drawing (anatomy, shading, etc.).
Carry a blank notebook and pencils with you everywhere, and draw, draw, draw.

If you wish to work digitally, get a Wacom graphics tablet.

Agree with hvanderwegen,

practice drawing, the basics, perspective, shapes, anatomy, just draw and do all toon boom tutorials before you start any project in toon boom :wink:

this is what I am doing right now, learning to draw
