The animation was good

And the style of drawing was also good
But the story line had no sense...I mean
A rat knocked over the food...Then the alien cried :/
yer it's kinda weird, but still...good drawings of the characters eyes and that
PS...I think the guy below me is bitching because you gave him a 7 on the rocker :z
Don't blame him though...he is only 14....

I expected better

half of the animation had no sound at all. This made everything less dynamic.
you really need to work on your walk cycles. They're embarrassing.
I know it's your style but why draw all of the characters with massive over sized pupils. Is it to make them look cute? I think it is quite a childish look.
the story was fairly hard to understand as there as no dialogue.
the animation was consistent and slow moving and quite basic. You should change the rotation of the can falling so that there is no ease on the motion tween. The background was basic but well lighted.
I expected better from someone who reviews animations with such high standards.
Hope this review helped you and have a nice day:PP
P.S. It's ok to use linear and radial gradient in moderation

Uhm...

... nice animation and all... but it was bland "story" wise.

I suppose this was a flash for Tom's Epic Fall contest.

Best of luck.
