Horrible.
First off. It isn't hard to make an animation in Animation Shop 3... It's hard to make a good animation in Animation Shop 3. This was not a good animation and looked like it required only 20 minutes of work at most.
I beg you to try make something in Flash that is worthy of viewing and then tell me if Animation Shop is harder to use.
Anyway, back to the animation.
It was dull. It was the generic "I'll kill this guy with no storyline... cue sprites and lame action". It really wasn't fun to watch. Do you think works such as Waterlollies or Red Riding Hood, both extremely well animated flash movies would stand a chance if they had no storyline and just pointless, mindless dribble? Of course not.
Make a storyline, drop the sprites and maybe you'll do better.
I gave you a 1 for the fluency of your animation.
