I began my collection after receiving a Ryoga cel (Ranma 1/2) that I bought (because I want all stuff about this character) and didn't think that I'll go on the collection. Now, I'm very addict to cels. I really like seeing all the galleries on rubberslug. I didn't think I'll have my own gallery, because my collection is really small. But I'm proud of my cels even if I don't have a lot ^^ !
I am a big fan of Sailor Moon and Ranma 1/2, but you'll find a lot of Ranma cels. In fact, I collect all the items about Sailor Moon (figures, plushes, puppets, rpg toys), but it's more difficult to find some items about Ranma, so I decided to focus on cels. My favorite character is Ryoga/P-Chan.
My collection is small for the moment, but I hope to find some pieces with the help of time and determination ^^ ! However, I know that cels are expensive, so I think updates will be rare.
