I think the word for this one is "architectural." It reminds me of a mosaic tile floor. And also the arches of aqueducts. And, just a little bit, of porthole-style windows.

It's architectural in a more metaphorical sense too, in that it looks built instead of discovered, in contrast to more impressionistic or spontaneous-looking flames. It really reveals a large amount of technical apo mastery.

There's a lot of good subtle details. For instance, the slight grain. I know a lot of people look at grain as a defect, but I don't. Some fractals need a bit of grain to avoid looking overprocessed. In this one, the grain adds just the right amount of tactile verisimilitude. Also, I like how the colors showing through the main structures are not perfectly symmetrical, on either axis. It took me a few viewings to notice this but it really adds a lot to the image.

I know my reactions to your work have been rather hit-and-miss in the past, and I think I'm finally able to articulate why. It's not the flames--because those are great--it's the presentation and crop.

In my first semester of college, I took an introductory poetry writing class. It was a class that a lot of people took to get their gen-ed "arts and expression" requirement. So, after our first assignment, he asked, "How many of you hit the 'center' button on your poem without really thinking about it?" This really got a chuckle out of the class, we went on to talk about why we do what we do with our art, et cetera...

The reason I told this story is not some sort of anti-centering campaign (even though I have that reputation XD). It's mostly about thoughtfulness. Someone could spend hours and hours composing a poem... and then a few seconds formatting it without really asking themselves "Why am I doing this? Does it add anything to my poem?"

It's clear that you spend a lot of time working on the triangles and transforms for this fractal. The hard work really shows. But it kinda seems like there was not as much thought put into the crop. Is it centered because you thought about it and decided that it was the absolute best way to present the flame? Or is it centered because that's your default tendency?

(Interestingly enough, I have a default tendency too. Mine is rule-of-3rds instead of centering. I've been trying lately to get out of that habit and stretch myself a bit more with my crops. So, it's definitely not a personal critique. Different artists have different defaults and we all need to learn to work outside them.)

Anyway, the centering actually suits this image more than most, so maybe take the above with a grain of salt. It was more a general musing on the importance of presentation/going outside your comfort zone than anything specific to this image. Meant to be thought provoking I suppose.

Oh, one last idea! I think it would be cool if the "oval windows" were a different color from their surroundings. That probably takes some sort of xaos-fu that I have no idea how to accomplish though.
