If you are an artist then playing with line and color is a great way to experiment with ideas. You aren’t trying to accomplish something grand ,even if you end up with something grand. You are simply enjoying creating playing. No pressure, no expectations, no stress. One of the great things about this freedom is that it allows your creativity to flourish. As a result you can very easily end up with something pretty cool.
I have been playing with image making on my ipad mini for a few years now. I started by making digital portraits and eventually that led to overlaying patterns on top of the portraits that I would then play with. Eventually I started just playing with the patterns minus the portraits. This is what you see here. Let me know what you think!
