Mediocre
I admit that I'm not impressed when I don't find any sound or music in something. It was pretty funny, however, when you acknowledged that there wasn't any in the credits. The animation looked pretty rough, but I guess it wasn't terrible. If you ever need to do something like this again, I would be glad to appear as a voice actor. The coolest part was when it zoomed out into the alien's eye. If you could put in music/sounds and work on animation, this could definitley be something I would recommend.
