This is probably my favorite entry that I've seen so far. (Other than my own - but, I'm really impartial to that one, as, it's the first video that I've been able to do, and like, in years... having failed at completing anything for THAC 11 and BRAWL 2014)
Though it's animation isn't specifically anything to marvel at, (it's actually a little bumpy for the 'dolly' shots) it is pretty meaningful. Short and sweet, just how I like contest-made brickfilms. You really were able to do a lot in only 30 seconds, and that's really a great feat!
You're message seems to be a bit similar to mine, in a way - though, you choosing to represent a character/world relationship on a "human to LEGO" scale, I choosing a much smaller approach. (spare/misc. parts to other, more well known themes) It's nice to see another entry that really tried for a more "meaningful" celebration, rather than just a bland party, or a short slapstick.
I've rated it 5 stars. You definitely deserve them, even if there is a bit of room for improvement.
