Needs some improvement...
This movie was really well done. I know how hard it is to even draw a horse, much less animate it. While I was impressed with the animation, you need to learn some things about audio.
1. Voices need to be louder than sound effects
2. Some emotion in whatever actors are used, would be helpful
3. You can not merely talk up to the gaurds on the wall. Especially on a windy night. That one scene at the castle, people need to be yelling to one another.
4. What usually happened when gaurds spotted someone, they would call for their commander or support from fellow troops. They would not call "We're under attack" when nothing has happened. They'd usually say, "Who goes there?! Friend of Foe?!" then you can progress from there.
On the possitive side:
The book effect was pretty good
The animations are done really well
The horses actually look like horses
Everything was pretty much atomically correct
On the negative side.
There were a bunch of audio problems
Voice acting could have been better
There was/is a lack of old English
Subtitles need to be a standard text
And went by too quickly
Over all I am giving this movie an 8/10
