hm...
Not bad...
Good: The music and the concept. The music set the scene well and on the whole, the concept and the little twist at the end was well made, a very downtroden movie. Nice.
BAD: Graphics, mostly. Animation was simplified with tweens... may i suggest tinkering with FBF? Also the backgrounds were very simplified with little shading on the whole, so i would suggest using reference pics when drawing those as well. Character art was simplified, so i would suggest brushing up on anatomy and clothing physics with a book and polykarbon's website.
On the whole, this was an OK movie, but it showed effort, and i appreciate that. It's graphical limitations don't limit what you want to portray. I hope you take what i've suggested into consideration Improving your graphics woulda made this much much better.
Good luck and good job. I hope you do well in the future.
