Guys, if you're going to post fanart, please have the basic courtesy to actually credit the artist. I know I wasn't around for a long time to enforce that, but it's really not hard and it's seriously the least you can do to show appreciation for the artwork.
All right time to give this thread some CPR as it just died.
I'm revising the policy on crediting artists in fanart threads where the whole purpose of the thread is to post art specifically not the poster's (meaning it's implicitly understood the poster is NOT taking credit for it, and so plagiarism is not a concern.)
Attribution is strongly encouraged and should be done if you can. Artists deserve to be recognized for their work. But this is a huge internet and it's not always possible to know / derive the provenance of images.
What you can do, as a user, is this: post the cool fanart image that you found, and if you figure out the author later, please edit your post to mention who it is so they can get some love. Maybe link to the place you found it (if it's SFW) if people want to do more digging.
All that said, here's a neat one I happened to find kicking around.
These are by a pixiv member, who, as best I can tell, is called "12". She also has a tumblr which they call "Rakugaki" and goes by "nemunemu1012" on twitter. Pixiv and Tumblr both contain some NSFW adults-only artwork, but I don't think this user has anything explicit on either, though they certainly have some suggestive works.
(That said, if any staff member thinks I should remove the direct links above, please feel free to either remove them or to warn me to remove them, with my apologies.)
Here are some neat examples of her work! And she has a whooooole lot more than just this! Most of the Pixiv images are of Zoisite and/or Kunzite, but she has a few drawings of other characters, too.
There aren't as many images on the tumblr, and some of them are the same as on the pixiv, but there are also unique ones:
She also have a couple more on twitter if you scroll waaaaay down, but most of their twitter pictures are non-Sailor Moon art (though her art in general is pretty good).
