One does not simply give three stars out of five.
The biggest problem comes when you yourself know that your animation is unfinished, but you still upload it here. Why? Just finish the project, upload and then add things if people ask for them. No need to store unfinished stuff here.
Suggestion for the flash:
1. Sound effect and music. Every flash that doesn't have any sounds is crap.
2. Speechbubles. Just something to make the reading easier.
