If you're a beginner and there's a problem with your finished work, it’s likely a user error. This may sound harsh, but the airbrush is a tool that can be very hard for some individuals to master, even those with a great deal of natural artistic talent. Think of using an airbrush as like learning a skill in sports. You don't start off with a perfect jump shot – it takes practice. There’s a pretty steep learning curve when it comes to using an airbrush, so don’t beat yourself up over early mistakes.
