better than I expected, actually
You've got a lot to improve in terms of quality. Voice sounds should be more smooth - the quality of the sound makes a lot of difference here, trust me, there are some animations where the voice acting alone made it very funny and enjoyable.
The graphic isn't bad, considering your idea (soups talking).
Oh, and about your idea: simple, yes, but you can make magic with that. For example, who doesn't know Annoying Orange, a youtube success? What was the initial idea? A talking orange that annoy other fruits. And it achieved a great success.
The problem on your animation is the way you organized this idea. The way you presented is OK: a short comedy movie. This kind of animation is usually the best for comedy (look at explosm flashes for a good example).
To improve your organization, try to plan ahead what you are doing, and make others see it before you make it public, see teir reaction. Sometimes we think a joke is funny, and you laugh among your friends; and when it goes public, its just not that good. It happens. Maybe happened here.
Keep working on it, don't give up.
