Quite impressive!
You've done a great job of combining stunning nature shots with interesting views of the child and yourself, operating the Phantom. My only suggestion would be to shorten the opening footage of the lightning storm. For me, the real beginning of the piece is that very dramatic footage of the Phantom flying away from us, over the lake. Although quite impressive, the lightning storm felt tacked on and too long, or perhaps just out of order.
I think you are a serious contender!
