New pool: "Reitaisai 7 Picture Gathering"?

Recently there has been many Touhou images coming from Pixiv containing large sketches of single Touhou characters in PNG format, all being labeled as above. Would this warrant a pool of its own, or would you prefer for people to search for it using tags such as "highres + transparent background"?

Examples: post #587391, post #583389

Under the circumstances, I think a pool would be appropriate here. Make sure to note what details you know of these in the pool description, as well as providing a link to the pixiv tag listing for this.

Pool is fine.
