"Minchin", by Molly Hollibaugh, has been around a while, and I have used it before. The greater challenge was to create on a black tile. I didn't have a black tile, so did colour on white, working through the colours of the rainbow being adjacent. Later I managed to find a piece of card I could adapt. As it was rather smooth, I chose to not shade.
My finished large zentangle inspired art piece using Dylusion Paints. Picture is a little darker than the original. Not sure if I like it or not.
