And ... that's it ?
Ok, I'll try to find ideas for "constructive criticism", it's pretty hard but I guess you're used to it.
So eh ... I think you should start by lowering the filesize and a good way to do so would be to lower the quality of the music you use. You might also want to improve the graphics ... and may be actually put more than one frame in you movie, 'cause with just one frame we can hardly call it an animation. Another thing you could try to improve is the plot of your movie. You know, it was really interesting and it kept my breath away all the time, but I think you can do a little better though.
So, overall it was definitely bad bad bad, but you can get better ! All you need is to actually put a little, little effort in your work and you'll be able to do something thousand time better yaiy !
