I've been poking around and have come up with a LOT of good sites! *glee*
Endorphin Shock Phenomena - The sitemistress of this place is most definitely a Russell fangirl. There's random doodles of a lot of people, but mostly of him--and apparently she likes to put him in pigtails. Inzaghi and Mizer, too. And all three are very indignant about it... *laughs* If it won't give you brain damage to see the fencer men done up all girly, go visit the We Are Magical Fencer subpage~.
Sentimental Gogo - This artist really... REALLY... likes Cruz. But their art is pretty adorable, so we don't mind seeing him drawn a lot. There's also quite a bit of Milanor/Yggdra on here, for those who like that pairing.
Vientiuno - This artist has an unusually masculine, mature style that we don't really see too often in anime today. There are lots of drawings of the Imperial Army here, including a truly gorgeous one of Gulcasa~.
mochi usagi - Most of the art here is of class types, but there are some of Yggdra and Rosary (no, Suzu, not like that) and the obligatory Rosary-is-into-S&M omake strip.
Tonurikosuta/R+ - PAYDIRT. :DDDD Not only does this artist's work look much like Kiyuduki Satoko's original designs, but she draws EVERYONE and posts new doodles once every few days. I am dying from the adorable. *_* There's loads of Roswell/Rosary and Russell/Flone in here, with some cracktastic Imperial Army stuff and even some Roswell/bananas stuff for laughs (seriously, I didn't even notice until I found this site that he LOVES them--he gets a 6000 Morale bonus if you give him the Banango from BF32!). This is the artist's blog/doodle board, but there's a link to her website in the upper right corner.
