wow, its a very nice, fast-paced, fluid animation.
i like the backgrounds, the details in the character design of the knight/dragon/birds, and i also liked the wild action that was going on in the movie.
also, both the knight's running/fighting animations and the dragons moving animation were good.(and i also liked the part where he was exhaling smoke through his nostrils), everything was perfect.
overall, a good and adventurous movie, i would like to see more stuff like this.
