Using a variety of tools for drawing and mark making will be unique to each artist whatever medium you use. One can leverage this by taking it through to your artwork, whether it's an illustration or surface pattern. A little brushmark from the flick of your wrist when you are just having FUN ( during the 3 minutes ) captures your personality ( I feel ) and becomes part of your unique brand, which is surely a good thing. You will only need basic PS and Ai skills, unless you decide to make your icons into a pattern ( I will not be teaching how to make repeat patterns in this class) Please have fun and be yourself!
