I decided to draw a few fanarts that kinda blend the book universe and the movie universe. In the book universe, all the teen vikings had a dragon to train. They had their own special dragon. So I decided to kinda give them all one :
Astrid doesn't exist in the books, but the girl from the books, Camikazi, as Stormfly, a Mood-Dragon, Mood-Dragons change colour in different moods. Snotloud was pretty much the only viking with his dragon fromt he book. Fireworm is Snotlout's Monstrous nightmare. He's pretty cocky.
