I dunno see you can't find Cel images of sephiroth why? because he was a game villian so sense there are no cel images any other kind of image that is worthy is hard to find... Lain was made on computers so they didn't have Cel images which makes it impossible to find any although I have found some pretty high quality images.
But sense I use sephiroth and Lain I've never created any sigs with out one of them unless you o**** the Blink one... So I normally now dun use images cause I'm sick of looking for them. Anyways comment on my new one.
