I'm a visual artist living in Cornwall, in the UK and working in collage and printmaking, drawing, painting, digital media and photography.
What a great tool the iPad is for exploring ideas. Here you can see how I made 4 drawings change from simply black and white to colours. They were done in Procreate, pure and simply, no fiddling about in any other apps. I made most of the brushes.
Your playtime results are fabulous!
