Another great source for those who want to upload more works by an established artist: http://www.hhhhhh.fr/h/auteur2.php?auteur=Murakami%20Suigun (a French-language site).

According to a number of online sources, "Lily White" is a 2009 artbook by Murakami Suigun. I would not necessarily think this image has anything to do with the Touhou character Lily White.

Please tag the pic better if you can. In addition to her name, I am unsure about some pieces of clothing she is wearing.
