Opening scene.. Trim off the end a bit, it is too long with nothing new being revealed.
Scene 2.. You can easily trim 2/3 of that scene, again, nothing new being revealed after a few seconds. I would suggest trimming off the back end when it goes into shadow.
3.. Agonizingly slow, you could speed this up at least 3 times faster, maybe even 4.
4.. Trim off the start, some of the trees, start where is gets closer to the structure.
5.. Perfect as is.
6.. Cut out completely, it is not telling us anything and top is too far away the whole time.
7.. Far too slow, you could probably speed it up x 2 and possibly trim the start and end part as well.
8.. Trim away part of the start, maybe to halfway up the green roof.
9.. Far too long, I'd say trim off the start, almost until you are side on to that tower.
10.. Now here is the change! I think you need to take scene 10 and reverse it so that you are climbing up to it, then make this scene 9. and take scene 9. and make that your ending scene 10. as you fly around it and then fade to black off that. I believe that will leave a more impactful ending to your film. With that said, you will still need to trim it slightly.
Of course cutting out what I have said will, in my opinion, give you a much better film, you still have the music duration to contend with. To drag things out a bit, I would suggest adding a little longer black at the start and show the title at this point, in the black, plus trim off a bit of the start of the music, so you bring up the sound as the music has already stated.
You can cut out almost half of that start of the piano intro, before the violins come in and open from your black and title, to the scene of the grass as you fly forward. Where your current film has the title ending on the tower, that is the point that you should be fading from start of the black and title into the grass as you fly along.
To see where else you can extend the whole film, after the editing I suggested, see if you have any additional footage that you might be able to throw in, a few seconds at a time to add fill to balance out the duration of the music.
If you don't, you can always fade to black at the end and then add in some info about the church you just filmed, such as its history, date it was built and anything else that may drag things out at the end, to take the film to the end of the music.
To add length, you could always go back and shoot some slow panning interior video, to add the fill shots that you might need to replace the bits you trimmed off this original video. However, make each interior shot no more than 2 seconds each, maybe 1.75 secs each to keep interest. You decide where to show/insert the interior shots in your video. Then I think you will have improved this whole thing, to make it video 2.1 Mark III Turbo. Hope I did not go over the top here, but definitely swap around scenes 9 and 10.
