It also seems a little as though you have rushed some aspects of this, especially the beginning. You have a good opportunity to describe everything here, but for some reason you have chosen to jump potentially important bits of the story?
Nitpicks seem to have been taken care of already, but I'd like to see some more character development. I found some of your descriptions of them at little too indistinct and I think you could definitely add to them!
As for originality I know it's nearly impossible to create something that hasn't already been done in fantasy, but you've done a good job in making this interesting. Keep typing!
