Impressive
Even if it's only for the effort, I think this movie deserves a 10.
The graphics and animation are quite stunning, with the specific style that can be seen in your past flash animations. I think you have always been improving, though - which is normal. There is a bit too much time with that close-up on the knight's face when he's still hooded, but that's just about it.
About the music, I think its good enough. The voice acting is average, and there seems to be some gasping in the sound playback, but it's hardly noticeable. And a little remark - there is too many bell ringing in the movie :P If you had kept it for the beginning and perhaps the end, the effect would have been a lot better.
Some scenes in this movie remind me of Bersek, but oddly enough, the main character reminds me more of Zidane Tribal from FFIX (at first glance). The fight with the centaur girl was pretty cool, even though it was a bit stupid for her to have her face covered - it would make it almost impossible for her to see anything, so it would work as a disadvantage. She wasn't wearing any armor in the rest of the body anyway. As for the fight against the king, it seems to be all good, but in the end, when the king is stabbed, we hear a 'CLING' sound (two swords hitting against each other) and then both characters land and after a while the king collapses. I think the sound that was heard was not appropriate, since the sword actually stabbed the king - unless the king is made of metal!
Overall, it's another job well done from one of the good artists of Newgrounds. Keep them coming!
