It's absolutely gorgeous. Wonderfull image and great tough to it.
I am such a pain, when it comes to details, that I wont use it and just leave it to you and the others who don't care about things like "little black text on a image that otherwise radiates a clean and clear feeling. As much as I totally understand the why, it always makes me sad. I wish there was a version of this with your name signature somewhere where it's hidden in everyday useage - like small and in the top right corner (if wallpaper is used in ubuntu/gnome-shell/any desktop with top panel) and thus still being identifiable as your work, easily noticable whenever opened with any tool or viewer, but not spoinling any of the quality.
Another option would be a less noticable, glassy-embossed way - maybe. Watermark-ish. Would still lessen the "clean" but not as badly as black text, I guess.
Perfect: Watermarked Text in a 'usually hidden place'. That way even transparent panels would still work AND your name would not be omitted.
Yeah, I know, I'm bad... getting picky about a little bit of text here...
Maybe you do understand what I'm getting at with "clear feeling" vs "visible text".
I have a deep respect for people with skill and taste who can create something this beautiful. And are willing to share. Thanks.
