Some really nice views. If I may offer a few suggestions; The opening scene might be more dramatic if you did a speedup of the opening and then slowing as the city came into closeup. Also, some of the slow pans of the city might look better if the were sped up, perhaps 2 -3 times faster. I expect people get impatient when the whole scene is being viewed.
And one last thought. I would consider that your credits are way too long. Bring it on screen quickly with a flourish and then let it sit for 3 - 5 seconds. I might ask myself: is this an animation project or a video project.
Keep flying, you have some great videos.
