Well, you are braver than me when it comes to trees! I like the shots you did and the way it was edited. I do have a couple of comments, as you did ask!
Firstly, the opening was good. I liked the way you showed the shadow of the drone. How I would have ended that was a second or two before, whilst it was still moving. A fade out or other transition. I know it's being picky.
Secondly, the totem pole thingy looked interesting, but we didn't see much of it. I would have liked to see a point of interest rotate, or a lifting up shot.
Lastly, how about fading out the last shot? I always find abrupt endings - well, abrupt!
Very good (and brave) shooting, and good editing
