Happy to give you some constructive criticism. Gonna start with a strong positive. You seem to have paid attention to shooting into "balanced light" so that your skies would expose well with your ground.... very nice. Also there isn't a lot of "searching for a shot" shown in the video. Many folks still film their "searching/scouting" shots and then use them in the edit. Now to the criticisms - remember all this is to help make you a better shooter!
So #1 I see a lot of "flashing" happening. This is either coming from micro adjustments to exposure caused by having the drone in an Auto exposure mode, or moire. Also I was getting some weird stutter/frame skipping. This could totally be YouTube but it could also be shooting in a different fps than your project was made in. Third is "video composition" Composition is important to video just as much as photography. Last I'll mention duration and pacing/rhythm. The video is a bit long. I'd actually recommend keeping it under 2 minutes unless you've got something spectacular to show.
Now tips addressing each issue... Flashing: Shoot in manual. This eliminates micro adjustments happening in the clip. Moire, don't shoot over-sharp, shoot neutral to soft, sharpen in post. The sharpening "in drone" is artificial Premiere will do a much better job sharpening your video. Frame skipping / stutter: shoot with a shutter speed apx. 2x your fps, 30fps would mean 1/60th shutter speed (or just under or over depending on what is available) - if your lighting won't allow that shutter speed, add ND filters until it's as close as possible. There are times to break that rule but start by using it - then break it. Make sure you edit your project in the same fps it was shot and don't mix fps. Otherwise the app will need to calculate frame-blending which isn't optimal. Once you've seen it you can not un see it and you'll notice it in news footage from now on. (I recently did VFX on a project and rendered the VFX at a different frame rate than the project - big big big stupid mistake had to do all the animation over at the correct rate - so pay attention to that! lol). Composition. When possible stop each clip on a completed composition, not after the composition is passed. You can start on an incomplete composition but with the subject either already in frame or slowly emerging or appearing, but grabbing the attention as early in the clip as possible. As a general rule unless you are ending the video, or changing subjects, don't "leave" the subject at the end of a clip. I think you had a pass at the first building that ended with the building exiting the frame at the bottom, then the same building appears in the next clip. Simply using that "exit" for the last clip of the building would tell the "story" better. The exit on the frame is the punctuation at the end of a sentence so also consider how the subject exits. Is it a "?" a "." or a "!".... Flight tips for "easy" composition... Lower.... Slower (usually not always). Also flying through frames... So setup a composition that is framed by objects on the left and right then fly through that frame, towards the subject, to reveal a second even more satisfying composition (hard to find and set up but such an "ah-ha" shot!) You can also rise-up /fall-down to provide that sort of reveal. Last point, pacing, choose clips that match the pace and feel of your music of vice-versa. You did that well in a few spots and I'm sure you can "feel" how nice that works. When you get that synergy it's super satisfying.
I generally don't post much "drone only" work - my work is usually with a small team and the drone footage is only a part of the entire video. But here's a recent piece as I don't feel it is fair to offer a criticism without showing one's own work. You'll even see where the editor took some of my wire-cam footage (all interiors that look "drone" are a camera on a wire rig) shot at 30fps and retimed it poorly and caused stuttering (grr) but when you work on a collaboration as a DP or CameraOp (both in this case) you aren't directing, producing, or approving the edit - so stuff happens! I'm not a fan of the animation either but overall it's a nice piece.
Good luck and keep filming! building those skills is so rewarding!!
