No offense, but I wouldn't call that "cinematic." Just looks like someone practicing flying a drone. I don't think you needed to speed up the video. It would have been smoother if you didn't. If you're going for cinematic, think slow, steady shots. Keep them wide. In fact, if you shoot very wide shots and keep the most interesting part in the center of the frame vertically, you could letter-box the video giving it that faux anamorphic look. To transition between shots, use a slow (1-sec or longer) dissolve, not crazy effects. I did like your "National Geographic" style graphic at the open.
