Good but unfinished
You did an excellent job at creating an atmosphere and making your flash cinematic - it is too bad that your animation isn't as good as your composition skills (or perhaps it is simply because you were rushed). It would be easy to fix, too - first in the beginning, the hoof should tilt before it lifts off the ground (otherwise it doesn't look like walking), and second in the final sequence (you should at least have one drawing of the man in a jumping position so you can alternate between the standing & jumping positions).
Having said that, the drawings are very nice and I love the way that you make the minotaur's head bob up and down when he walks. Good sky, too. :) Did you import jpegs into flash to get that look?
