I should really see the footage before I judge this track, but here are my thoughts. The windchimesy sound in the beginning and throughout sounds cheesy and diverts my attention, I feel. I'd get rid of it. What I'd also get rid of are the synth strings that come in around 1:45. They sound somewhat out of place. Maybe you could use another patch, or perhaps make them a little less noodly?
But mind you, these are just a few points on an otherwise excellent tune. I loved your crisp, clean production and piano parts. Sounds kinda like the music you hear on documentaries on Discovery.
