I gotta link a great site now: Modelos de Papel!
It's in spanish, but don't be afraid, it's easy to navigate and with over a thousand models, you might find something interesting. There's a lot of origami patterns too, and surprise: even Warcraft models :P
I really like the Ancient of Lore one which looks a little like that ->
They're under the Anime folder.
You'll also find alot more links to some great sites too.
Have fun, and some new models later.
