How I Created my custom brushes!
There are lots of advantages of creating your own brushes, if you use only brushes you have created yourself, there will be no need to state that you have used another persons brushes (which are possibly copyrighted) and your artwork will be entirely your own. Creating your own brushes is also relatively easy, you could create your own detailed brushes, this is good because you wouldn't have to rely on somebody else's creative opinions on what looks "good" or "professional", and it also gives you a lot more creative freedom. If you create your brushes from scratch they will be entirely your own, by creating a sketch, then scanning the sketch in a developing it into a brush preset your brushes will be completely owned by you, whereas using an image off of the internet for example Google, may already be copyrighted. It is helpful to have brushes at your disposal because they create repetition very quickly within a piece.
