Ok. If we're appearing a bit judgemental here, Misha, it's because this is a section where people post their work for criticism in order to learn.
If you made the video, people are normally happy to give advice, but you're going to start on the wrong foot if you post it claiming it's "great" (unless it genuinely is great).
If, on the other hand, it's someone else's video, there's very little reason to post it (apart from the rare exception when someone want's to demonstrate a point or show an example of something particularly good/bad)
Personally, I thought the vid had a certain "cuteness" and obviously took a bit of time and patience to make. If you want advice, tell us what yu're trying to achieve and there are many here from rank amateurs like me to seasoned pros like some other people.
