I've been wanting to make a unique watermark for my digital artwork for a while now. I'm a fan of the more artistic watermarks over those that are just the artist's website/gallery link. Not that there's anything wrong with that, I just like a little flair better.
Anyway, these are what I came up with and I'd really like some feedback! Feel free to tell me what sucks, if they wouldn't work, if there's one you really like, or if you have an idea for what I should do instead. I really have no idea what I'm doing, so I'll take whatever critique I can get.

All the white is actually transparent, I just put in a white background to see the designs better. I would be making these smaller, fading them, and adding the date if I used them of course.

I'll move this to scraps after I get some feedback.
