an ok short
really needs more than one fight scene to make a movie. The explanation of why they were fighting should have been in the movie itself. The backgrounds were cool. The characters were a bit grainy looking but I can tell they were well drawn. Good detail in the characters as well. The scene where the guy summoned up his power and you could see elements rising from the ground was a nice touch.
As far as interactivity, no scene selection was needed for it was too short. It was as interactive as needed for a movie. You might add a status bar for the preloader and consider adding your text intro for fighting in that section.
Nice sounds worked well for the movie and the bit of music set the tone quite well.
OVer all, its a good start for a first, you should keep at it!
