Your airbrush will have a back lever as well that acts to shut off the air flow and paint flow when the trigger is released.

The great thing with airbrush art is that you really do not have to know how to draw. All you need to know how to do is successfully use the stencil that you wish to use for your design. If you are doing a stencil for say a dog then you would want to take your time and make sure that the eyes were the same size, the nostrils were cut out shaped the way they should be and so on. If you rush you could end up messing your stencil all up. The stencil is to aid you in creating your airbrush art and is a big part of the art process.
