Good, but needs improvement
This was a pretty good flash. Contrary to what the last reviewer said, I think your models are actually quite well-done. However, there are some other issues you need to fix.
One is framerate, as others have said. Your movie should flow smoothly, with something like 15 fps being minimum and about 25 being optimal. That's a lot of work, but it would greatly improve the end results.
Another simple thing you can do to improve the movie is to make the camera more steady. Whether this means buying a tripod (mini tripods aren't too expensive) or rigging something up (set the camera on some books or a box, or something like that) it would greatly improve the quality.
I agree with the last reviewer that you should try to find someone else to help with voices, so that there is more variety.
Also, you could try making the intro a little more interesting, and make the music flow better. The guitar-playing shouldn't have stopped during the title screen, but rather have gone on playing through that whole section, for example.
If it is worth it to you, it would be nice to see your animations captured with a better camer, also, and your audio captured with a better mic.
There's a lot of potential here for some really good claymation, so keep up the good work and I'll be watching for another from you!
