UPDATE 3/6: Unfortunately, we had to remove them since the artist removed his blog post. But if you still want to find them, I have two words for you: Google cache. Hi to those from Burbank, and good luck with the show!Here are five new storyboard pages from Fred Reyes's portfolio blog. They appear to be of Hiccup riding Stormfly, although there's a mysterious second Viking riding behind him as well. Unfortunately there's no episode number for this one. However, unlike the Episode 10 storyboard, this one seems to start of right in the middle of the story, and not at the very beginning.
Thanks to Mina on The Night Fury's Den!
