This is one of the more ambitious films in terms of scope, but it's really well crafted.
I'm impressed not only by the smoothness of the animation, but also how much of it there is. A fully animated 3 minute brickfilm is hard to pull off in 24 hours, especially at such a high framerate (is this at 24fps?). You pulled it off, though. There are some minor issues like light flicker, and sometimes the backdrop moves around a bit, but those things are hard to smooth out when you're animating at such a high pace.
Wonderful entry.
