Sabrina/Natsume: From Pokemon episodes 22, 23, and 24. Actually, I'm looking for just any production art from these episodes under the assumption that I have a better chance of winning the lottery than being able to find something of Sabrina herself. I have seen one cel from episode 23, but unfortunatly it was NFS. I am also looking for any production art of the ghost Pokemon or Abra and its evolved forms even if they are not from these episodes.
Tomo: From Fushigi Yuugi, episodes 37-41 (I think.) He also makes a few appearances in the OVA. I've *just* missed cels of him for sale at least two or three times. I would also really like a cel of his disguised form Aino (sp?) from when he is inside Miaka's illusion.
Martel/Marta: Full Metal Alchemist, episodes 30-34 and 38-40. The snake chimera who spends at least two episodes stuck inside Al. I recently got a rough of Roa/Law, which was pretty close (thanks Sakura-chan!), but I would still definatly want any production art of Marta if it came up.
Akane/Sister Angela: From Sailor Moon episode 176. For a character of the day, she has quite a bit of screen time. Again, have seen a cel of her, but it was NFS. I'm not really fond of her phage form - I think it looks ridiculous. I would probably only buy a cel of 'Sailor Director' if the price was quite low.
Well, that's it. If you've seen any production art even if it's not for sale of these characters, I would still love to see it.
