I don't see why not... I've seen people trying to sell erotic webcam sessions, subscriptions to porn sites and adult domains without real problems in the past... Just make sure you don't post NSFW images, and make sure you do add a nsfw tag to your post.
This being said, i don't know if there is a market for nude art prints, i do think a lot of people won't believe you are selling "official" prints, and just assume you're counterfeiting.
I'd suggest trying to find a trusted escrow that has at least a basic knowledge about rating art to help you handling payments and disputes, with your current rank and trust level, i think your selling thread will be doomed from the start if you don't have an escrow at hand.
