I have the weirdest feeling I've seen this before. This might be because I followed the 'Fractal Flowers' tutorial with very similar colours and, though I didn't post the version that looked like this it did, well look rather like this. Are you using the tutorial? I notice you have a number of these.
Perhaps unsurprisingly, I commend your colour choice. I was astonished at the lovely effects I could get - as your example shows here. Nice job.
