As Moyrust said, it is a tad like The Unknown, but that's called inspiration. In fact, I'm making a film almost similar to a film added a while ago, but different in many ways. In the beginning, it looks to me you used the easy way out of animating a walk cycle, by just having the camera shoot from the waste up, and having the arms move. It looked like it could pass. On that note of the introduction walk scene, the walking noise didn't "match" well. I suggest trying to make your own, since I believe that is "stock" audio of walking since I've heard it before.
A small detail which I hope you pay attention to in the future is the cutting off of the audio. This could have been because you filmed before-hand then called for voice actors, or your voice actors did it unintentionally, not knowing. Another flaw of the film would be the blankness of the surrounding set. If the video took place in a wooded area, have a background image of a forest, and maybe a few lego trees.
The blink at the ended was pretty nice, though having it more matched in color could help. It's hard to match colors exactly, because based off your lighting and what was on your set could make it so it's possible every pixel was a different color, which makes it hard to have the post-production blend in more.
I suggest for you to keep on practicing, and then try to make a film longer than 11 seconds. Good job on this brickfilm. Even though I've seen the joke, this made me laugh.
