The opening should have been cut
The effort put in for a first flash definitely makes this flash deserve a place in the portal. However, the opening where the fish is drawn almost made me close the movie and blam it. In general, shape tweens should never be used when the tween scrambles things up in the process of changing. Some of the later blood tweens looked ok.
If the movie just opened up with the fish story it would have gone a long way to drawing in the viewer.
The choice of music was good and served as a nice backdrop.
