You can paint anything you want. Large or small. Ive been commissioned to do things ranging from tshirts, helmets, murals, flames and scallops on cars, model cars, even details on girls finger nails. You can spray fine lines or broad areas. Ive tried a broad range of airbrushes. The hf airbrush is a good feeler. Its capable of putting out quality work. But like any new tool, you need to first learn how to use it properly. There are cheaper models, but their quality and their ability to produce acceptable work are most likely going to turn you off to airbrushing before you even get a chance to fully enjoy the hobby.
