Mark, I know how you feel, I am taking Drawing 101 at a local CC and I am doing awfull! I can't find the dang trigger on the pencil! The air brush is a bit different, you don't have the feed back from the pencil against the paper, you have to use your eye and tirgger finger rather than your feeling of presure against the surface to adjust the value of the color. Anyway, do the practice lessons on howtoairbrush.com, you have a bit to learn about working the tool (airbrush) before you can apply it to creating art as you do with a pencil.
Please don't give up, once you master the mechanics of the tool, it will come much eaiser and faster!
