Limitations of the model, I'm afraid. Otacon's hair was a lot more scraggly, but since it's not part of the model, there's not much I can do about it. So, now we have a combed Otacon.
Concerning Ocelot, I contacted Darth Kitty, author of the Snake model I'm using, and he has an Ocelot in the works. I'm trying to get it from him and include it in the pack as its official debut.
