Even as a test, this set-up has a lot of potentials for sight gag... Over all not bad.

It's rather short for any kind of real judgment, however, so not much to reward or decry. It's only slightly worth pointing out the multitude of black-screen-of-blackness through most of the last half...
On the one hand, if it was a joke, ...um...droll
On the other, if it was filler to qualify for posting... um... not so droll

Most of all, giggle a bit, remember to breathe, and hopefully these thoughts can help you pursue something of a project to make everyone laugh out loud.
