I found a great new artist ("new" in the sense of "none of their work is on Shuushuu yet") named Miyamoto Ikusa (Ikusa Miyamoto?). Their site is at *removed* (careful if you go there, some of the images are not "safe") but I can't get most of their pictures off the site, they have some kind of right-click protection.* Now I guess that's okay if the artist doesn't want their work posted without their permission, but I just wanted to be able to share it with you guys.
* I was able to get this cute pixel-art animation of Miku, though:

but you know, not every image has a source and not every character has a name :3
