Really really nice job. Great flying. Color grading was great. I have only a few, quite minor suggestion and perhaps a small criticism.
As you come into 1:07 the exposure isn't there as you reveal the surroundings from the water shot (which was great). I would recommend cutting from 1:04 to about 1:10. I think a transition rather than a reveal might be more visually powerful anway (JMO). Then there is the transition into 2:03. You go from a lush saturated scene to one with exposure issues because of the dynamic range involved. I would advise to either do some masking and color grading to increase the contrast and possibly drop the exposure a bit in the highlights. I love the reveal coming after 2:10, so perhaps trim the start. I think some color grading will really help coming into this scene. A simple curve on that section should help, with or without masking the shadow area. I did a quick mock up to illustrate what I'm saying (photo below).
I love the traverse at 2:27. I'd recommend cutting around 2:36 or a second or so later. The vertical motion to the dead stop stopped the flow in this clip.
Sound effects:
Personally I thought the goose sound effects were A bit hoky, at or perhaps just overdone. If you use them at all, find a spot where they sound the best, fade them in for 2-3 seconds... then fade out- no more geese. When you over-do a special effect it's no longer special. A few short quiet moments with the geese will have the effect and it would have been a subliminal enhancement that the viewer wouldn't even be aware of. That's what you're looking for; your special effects not to go noticed.
Also, I would do something similar with the wind. Try fading it in gently for effect, then fade out and leave it. You'll have planted the message without having to linger.
Again it looks great. Really cinematic. You captured everything and told the story and I think there is so little you need to do to refine it. Congratulations on a fine piece of work!
