My favourite thing about drones and the interwebs is that I can see places from all over the world, some places I may never go (though I hope to one day visit India)!
A couple tips for video, in general (not just your video):
Watch your cuts. When changing shots from one to the next, it is a bit disorienting to switch between two very similar angles. You did this at one point over the parking lot. Try to avoid that.
Another thing is starting or ending camera movements mid-shot. The Spark gimbal doesn't have the finest of control, so it feels abrupt to start and stop mid shot. Plan the shot ahead and either keep the movement going the entire shot, or pre-plan the image you which to show.
Otherwise, nice smooth movement. Keep it up, keep being creative! Hope to see more of your city!
