Thank you very much for your nice yet still honest comment. Yes, it is a bit dark. I yet have to find out how to work with the lighting ... While I need some encouragement from time to time, false compliments won't help me to improve. So thank you again. I could need more comments like yours, for every medium I am working with.
Like almost everything is a matter of practice. To be true, I only started messing with fractal software, because I more likely can do it in-between than writing a story or drawing a digital picture (other than crappy muro doodles). Because I can approach it like a child: playfully experimenting with it (while being faszinated of the beauty of math).
