Doesn't look like it's NSFW.

Is this really deserving of a NSFW warning? I mean, the only thing that would even make it come close to deserving it is the fact that she's showing cleavage, and even that is far from being extreme, and it's far from being the main focus of the piece. I don't see blatant fap fuel when I look at this. I see a well done piece of art of an attractive woman.
