It is for this reason that the bottom feed is also referred to as a siphon feed. Since the artist can attach the cup to the bottom of the airbrush the colors can be changed quickly by using different cups prefilled with the colors needed. Airbrush art also uses airbrushes with a side feed. The side feed has a cup that mounts on the side. Sometimes you just need to step back and take a breather to get your inspiration back. If you find that you are not getting inspiration no matter where you are looking then it is definitely time you stepped away from the airbrush art for awhile. Take a few hours to do something other than airbrushing and let your mind go for awhile. Once you are comfortable using the airbrush then you should work on creating shapes with your airbrush. Using a cheap surfaces airbrush circles, triangles, squares and rectangles. While this may seem stupid it will help you to learn how to create designs using your airbrush. Continue to practice with shapes until you are able to perfectly render airbrushed shapes. This is why airbrush art fits for just about everyone around. Classic paintings can be airbrushed onto canvas to give for great wall art. With airbrushing the paint goes on to the canvas more evenly than if it had been hand painted. Also the time frames are shortened when the paintings are airbrushed versus hand painted. You should not have to take your airbrush apart every night to clean it, it is alright to only do a complete break down and cleaning once a month. Just make sure you do not go any longer than that. When you take it apart to clean soak it in a commercial grade cleaner overnight. The next morning take an airbrush cleaning brush to it. Buffing the nails will give for a rougher surface for the paint to cling onto. Prior to actually airbrushing the nails, a base coat should be applied. There are actually two reasons for the base coat. This base coat will help protect the nail from the paint and help the paint to adhere to the nail better.
