Good job - you will do better.
I really enjoyed the art in this clip. The animation was not that bad at all - and you can tell that the artist is getting better and will be better.
The story was well portrayed considering the length and the lack of dialogue. The story itself left something lacking - any semblance of reality.
Chopping a dude in half? Pike men that are apparently completely deaf - they didn't hear a charging horse coming up behind them? A repeating crossbow with, what, fifteen bolts?
The fighting was really silly, to me. I had the feeling that the artist was more interested in telling the basic plot than in really telling a story.
I did like the shooting of the dude off the lookout tower.
All in all it was okay and watchable. The biggest problems I felt were related to the artist wanting to get the fighting over with as quickly as possible.
Put a little more effort into realism and you're going to be doing great.
