These are Doujinshi that are simply short, doesn't mean they're bad, it's just that there's not much to them to really make a theme or more then a few chapters. Some simply haven't had a lot of time to get started, whereas others haven't updated for years. They're worth a read, even if for art only. I'll try to keep the cap around 20 pages.
Sailor Moon Re-Destiny
As of right NOW there's only 6 pages plus a cover, but the art is done very well. It's worth a look. heart
Sailor Moon xX (nyu)
This is a very short manga but it introduces an interesting plot device.
Sailor Moon: Star's Rain
This is only 3 pages long but the art is really pretty~
