Same here.
But some remarks if I'm permitted.

1. I find the rotors turning a bit slow in comparaison of thee speed of the "vehicle"
2. Near the end of the animation, when the whole ship is visible, imho the shodows are too crisp at the borders (of the shadows)
3. Near the end of the animation, when the whole ship is visible, imho the ray of lights that are coming from the end of the wings...are kind of impossible, they are used in foggy weather, mist and/or steam situations. Your seen is bright sunlight!

Besides that I really I'm impressed with your movie. How long did this take you to render? On what machine?

Talk soon
