She is. He tends to do a lot of "risque" poses, some of them going well into the realm of pornographic. Sometimes it's sexy as hell, sometimes it's just in-your-face and Hustler-esque. He apparently likes the overly-used backdoor look (that phrase can be taken a variety of ways, none of them good), if his gallery is anything to judge by.
Wow... I just took a look at his gallery on Deviantart and yeah... Not my cup of tea. Most of his stuff is quite pornographic indeed. And the overly-used backdoor... just too much...
Artworks like the bare-*** Emma Stone Gwen Stacy, or the naked Sucker Punch girls are actually quite distasteful and juvenile IMO.
