Interesting and fun concept! I like how the animation starts off as a sketch and then goes to realistic rendering. The producer/s of this video also added some stills in between sequences. A signature move that one might notice is the way the director moves the camera through foliage until the building can be seen clearly, this is done several times. One thing I'd like to point out is the cool 'moving sky background' that happens near the end of the presentation, nice touch. I will say though, that it would be nice to see this animation done with closer frame gaps to improve the smoothness of the animation, but of course that would require more time and computing power. Thanks to "Homeworks" for posting this video up in YouTube.
