Cute!
I think this is very cute. Though, when you say promo, do you mean a commercial promo OR a promo that is before the "Feature Presention" (aka the main part of the flash)?
As a commercial promo it's good but seem alittle long for something that would appear right before a flash movie. Most of the time when I see something like that, they go by quick enough that I see it, but that it doesn't keep me from seeing the main movie that I wanted to watch. Maybe shorten it alittle. That way you have both the cute AND it gets the point across without taken up too much time.
