Drawing is a very important skill in art generally. It really doesn't matter what you're trying to do even if it's a cartoon, you always go from the known to the unknown.
To achieve a good drawing, you start by just sketching as a guide. Your sketches may just be strokes like straight lines or curvy just to show movement or what ever you have in mind before you forget. Sketching for an artist is like taking notes, you know, like using stickies for a to do list.
It is from this sketches that you now develop your drawings to look the way you want them and from there further details, maybe for graphic design, animations or even painting. It's usually after you have become proficient with your drawing skills that you now develop other skills.
The drawing above was used to develop the animation for the intro of the movie below. We will talk about composition later.
