It's been ages since I've done anything other than random image manipulation in GIMP. A lack of inspiration, mostly, has caused this hiatus.
Although I hate the saying, it is rather true here: "Those who can't, teach." About 8 years ago, I made an image entitled, "Lifestream II." I received numerous questions about how to do it (couldn't remember how--a lot of trial and error, didn't save the xcf file). I didn't exactly try hard, however, and I've finally managed to mimic it.
If you're going to post this on your blog or website, please link to my website: [link]
or at least to this DA page.
Please note that I've provided this tutorial as more of a guide. I would really like to see something developed from this method using different filters, your own style, etc. This means I would appreciate it if you post a link to your deviation in the comments or something similar.
One final word: "Snow Dots" refers to a tutorial on my site at [link]
For the record, I'd rather call this "Phoenix Tail"
