I've been working on this image for a few days now. I 'painted' the back and then traced then cut'n'pasted out swirls from a black background on my antique photo editor. I created the patterns with the eraser. It's all 'hand-rendered' - if you can call it that - even though it's been drawn digitally.
I've still got some more to do on it, I might post the result when I'm done.
