This is just a test, nothing too special! :) The brushes here are an airbrush, pen, eraser and way more! I made a really nice sunset with this so...have fun with it! Using the variable sliders, you can change the size, opacity, colour or hue, type of brushes and setting your brush hue to black or white! Brush one is the airbrush, brush two is the pen, brush three is the eraser and there is way more! The higher the opacity is the more transparent it becomes and using the opacity, you can try to blend.
