Nicely flown and edited. I found the music to be a good choice and I liked your use of captions (even if I have no idea where the locations are).
As for the resolution, I didn't even notice until it was pointed out. My opinion is that unless you are doing commercial videos, you really don't need to publish in 4K. I usually go with 1080, maybe 2k, though I may shoot at higher resolutions. Gives me better options while editing. Most of those who see my videos will do so on smaller screens. I'm not convinced 4k would add to that experience. Just my opinion.
All in all a very good and enjoyable first effort.
