nice technique
ignore that last guy.
the 3d effect is not so much unusual but normally not the focus of the animations on ng. i dont know how much education he was expecting judging from the kind of flash thats usually submitted here.
anyway about the movie. it looks like a lot of effort was put in this and even for that its already a lot better than most. the movement was smooth but the graphics were a little fuzzy. i guess you had to make a trade off between quality and filesize.
it looks like you made this in a 3d suite program and exported it to swf. i would suggest you added more features like a preloader, backgrounds and dialogue but if you don't have flash it's gonna be pretty difficult.
it seems more like an exercise than a movie but if you had some better ideas or even a plot to it then you'd get higher ratings.
