Maybe it's because I grew up watching anime, but when I first started drawing, I began by practicing with cel-shading. That's why now I actually prefer using different art styles and exploring more variety.
Also, I share the same view as moontokkym and PeteLensing, which is also something I often suggest to my beginner friends: Seal away the soft airbrush! I'm not saying you should never use it, but at least try to avoid it as much as possible while you're developing this particular style.
