You're good, but not perfect.
Congratulations. Not enough people do the "fantasy" genre without ripping from Lord of The Rings. Faieres and a Centaur make this one a breath of fresh air. You're animation is a smooth as diarreah, something alot of artists need to work on. Fight scenes were wonderful. The sound could have been done better. More than anything, the voice-overs were terrible. The music was so muffled that it ruined the final fight. Good choice of soundtrack and SFX. Make sure to get better voices, please.
What the biggest problem was is your style. Using cliched anime styled characters make the flash seem very very unoriginal. I noticed portions fight scenes have been done to death in anime. One I'd like to mention is the lightning fast one-hit-kill samurai slashes often seen in duels. It's just not cool anymore to see a man normal for one second, posing with his sword, and then falling apart at the cuts. You need more originality.
