I would have replied sooner, but this a very busy time of the year. I thought it strange to get no reply at all (although the lack of criticism isn't so bad, LOL )

I used what one guy on this forum called the Morgenson generator: a fractal generator from about 10 years ago. It's command line only, but it gives more flexible results than Fractal Pro Generator. Then I went in and added some touchups with Gimp.
