Furatsuki's image is made by Meepy, I think. I searched on her pixiv but I didn't found it. You could ask her for re-upload that image through tumblr?

Kamitsuki's art is deleted from pixiv (I did not saw the image)

Irotsuki's art can be found here http://www.pixiv.net/member_illust.php?mode=medium&illust_id=10729717
