Your page was literally just a sentence and a couple of links. You provided absolutely no visual examples of the aesthetic in question whatsoever; that's why it got deleted. Also, as somebody who's been involved with the Vaporwave community and a lot of their subgenres, I've never even HEARD of Tumblewave so, to me... it comes off like you just made it up (and since it was marked as a Candidate for Deletion anyways, I'm clearlly not the only one who felt that way). If you want to try again with being a little more in-depth with the explanation and actually provide some images to back up your claims of it being a legitimate aesthetic, you're more than welcome to try again, but the page as it was did a piss-poor job of showcasing it.
