I made it to ten minutes, but I just got annoyed at your constant camera movement in every single film clip. It was far too much and unnecessary. There are times when this is needed or okay to do and many times when it is not needed and just gets frustrating to watch.
You had some great footage in there, but you do not need to keep moving the camera while filming. Sometimes you can have the camera still for a few seconds and then possibly move it a little with a pan or tilt up or down, but not every single scene.
Also, at the first minutes or so of filming, you are jumping from a left drone pan to a right drone pan to a left, etc. It is best not to do this, back-to-back. if panning right then maybe a straight on flight shot then possible a straight down and then maybe a left panning shot, but don't jump left, right, left right etc. or as I've seen some do, forward and backwards flight one after another, It is disturbing to the viewer.
An hour is too long even for someone extremely interested in the subject matter. Break everything up and put it into episodes. Also, try and tell a story with the footage, don't go summer to winter back to summer shots. I'm not a film maker but this is how I feel about the footage, so far.
I jumped through it a bit further into your film, and it looked like you still had some good, interesting footage. However, I did not have the time to stay and continue watching. Always try and leave your audience wanting to see more, when you end. That will bring them back to watch more. If you give them so much they have become bored, they will probably never want to watch anything else you produce, for fear of quickly becoming bored again. Hope this helps.
