How to do good highlights using airbrush...?

Ive heard great things about the airbrush.. It's one of the most popular tools for shading and highlighting images, and is used in nice background wallpapers located at Spoono.com ..... Im wondering how do you use the airbrush to make effective highlights..? What is the key to mastering it? I know practicing and playing around is one way, but Ive spent 20 hours and I cant do anything close to the beautiful images I see :(

the thing about any brush is to have good control over your motion - if you don't move it smooth you get bad strokes...a tablet helps loads if you're not so good with a mouse. Also you have to pay close attention to the settings.... _Many times you get ugly strokes when the opacity of the brush is not 100% and you pass over the same spot twice...

that's the problem i have.. when i go over a spot with airbrush and its too light, i go over it again and its too dark and everything is uneven.. sometimes when i air brush a section, let go of the mouse to brush another part and join it, its not even, one parts dark one parts light :(
