A Few Suggestions...
This flash does have potential... However, there are some pretty big problems that stand out. I understand that you're not really done with this yet, but I do have some suggestions.
1.) The dialog text needs to be bigger! Too much time was taken just trying to see what it said instead of focusing on the animation. If you could put in voices, that would be even better!
2.) It needs a story or at least a lead-in - so the viewer can understand what's going on. This is also tied in with the small size of the dialog text.
3.)It needs more fluid animation, and something a bit more than just black silhouettes on a white background. While it is a certain style, it's a tad cliché.
Anyway, keep on working at it, and I'm sure you can make it into something special!
