Well, I never studied or read books, I just kept drawing and drawing. I started out drawing exclusively from reference. This forces you to learn control, because there is something to compare your work to. there are hundreds of techniques, starting with basic shapes and adding detail as you build or using grids for precise placement, ect. the best way is the one that makes sense to you. because understanding why something works leads to confidence and consistency. I would thou suggest starting with simple things: cartoon, comic, anime characters, once you master line and proportion, move to more detailed subjects. you'll find that developing artistic skills as a global effort, will very much mirror creating great individual works, start simple and keep adding. detail, style, technique, color, will all come with time.
