Constructive critique:
Bin the Tiltshift effect - it is not just tired now, it is totally exhausted - and add a little digital sharpening. An altitude shot like this benefits from top to bottom pinsharp focus.
As you were taking this 'blind', i.e. without a video downlink, then obviously you have little control over composition and have to accept what you get. But as a note on that subject, composition would be made more enticing by framing slightly to the left to show more of the curve of the river.
And lastly, go out and do it again half an hour earlier, so that the setting sun illuminates the trees and boats on the waterline.
