This image's style is so bizarre, I feel like there's some kind of appropriate tag for it, even though I've only seen a few others like it before (though not on Danbooru). o.o; Any ideas... ?

It's clearly related to post #10671 but I don't know the artist, and though they're very closely related, I don't really think a parent child relationship are appropriate, since they don't have any progression from one to the other.

Then again, I'm not that familiar with the application of parent and child posts.

You're right, parent/child wouldn't be appropriate here. It's best to link these two pictures through comments.
As for tags, maybe creepy? shadow?

Creepy? Try awesome! :D

If we knew who the artist was, I feel that would be enough of a link between the images. Although I agree that linking it through a comment is probably the best way.

As for the tag, aesthetic tags (cute, creepy, artistic etc.) are really troublesome I guess. Perhaps we need to make a few pools that are public for this kinda purpose. "Public pool of creepy images" or something.

PS. according to post #42520 it's kashmir, but... None of his other images look even remotely like this, so I'm not so sure.

Definitely kashmir. There are versions of these pics with text on his site: http://www.picnic.to/~kashmir/img/uv-c.jpg and http://www.picnic.to/~kashmir/img/illbewatchingyou.jpg - I don't know if the pics posted here are edits or if he posted the textless versions anywhere.

Woo! This guy's awesome, thanks for the link.

You could've just clicked on the "?" next to the artist name, you know.

Yes, I am aware of that. :)
