This sure does have a spooky look to it. I kind of get the feeling it is an underwater scene of some kind. Maybe in a sunken ship or something. Anyway..it's a great Halloween image, and fractal.
I had to actually download the largest version, bring it into my computer, and brighten it up to make it out on Photoshop... being that I have my gamma more or less adjusted for CMYK print quality...Nice design...Thanks for sharing...
It's right for this time of year. :-) Black as a crypt. It was not too dark for me to see the black shine. I was looking at the shapes, which looked like ghosties and ghouls floating about...maybe you could work on them in Photoshop, and give them more of a spooky glow, and features. :-)
