I've just finished watching the Secret of Kells earlier tonight. It was a beautiful movie. It's amazing that you have worked on it! Good job! The scene when the monastery is invaded by the vikings made me cry. Trully a masterpiece.
Dammit I loved these they were scary as hell! I also honestly think that the baddies in the Spirit Realm in Zelda: Skyward Sword were somehow based on these, they really are similar in appearance. Anyhow great job!
