the thing about airbrushing is u have to have a good airbrush to give u good results!if its a cheap airbrush its not gonna perform the way u want it and then u get mad and imaptient and store it in your closet.another major is the paint u use.acrylic paints are much harder to work with then say urethane.urethane paint and solvent based paints are used for more automitive applications,it sprays much smoother and consistent.doesnt dry up in the tip as fast BUT,it does smell terrible so a mask is strongly advised.if u get a good airbrush/paint mixture its all on your drawings skills at that point!keep at it,airbrushing can be very rewarding,and profitable!!!!
