A bit of a mixture - mostly I start out with photos that I take on a Canon pocket camera, or drawings that I do with a felt tip pen on paper.

Then I usually edit them using a Samsung tablet. My favourite apps are Snapseed, Cartoon Pro, Mirror Lab, Glitch Lab, Chroma Lab, Go Art, and Deep Art Effects.

The pictures usually have around half a doz effects on them. But the key is Snapseed - that free app is brilliant and I almost always start and finish editing with it.
