You have impressive designs, a plausible animation, and awesome angles. However, this literally told me little to nothing. What's going on? What is this place? What are these inventions and buildings? What are their uses? Why are they here? What is this world about? Music would help set the tone. How about an inside look of the world to see what it's like? Is this a dystopia? It looks nice on the outside, but is it terrible and dirty on the inside? Is this a distant future where robots rule? Has the world gotten polluted by a great war or something? A voice over narrating would be neat. It may look aesthetically beautiful and all, but this doesn't paint a clear picture for what you're planning.
