What a incredible place, the vertical shots of the irregular roofs, and later the close ups of the equally irregular materials used.
Really nice camera work and flying.
I'm curious about he shimmering on the trees etc from the opening scene until you alter direction at 1:25.
It looks like perhaps overexposure on the light reflecting on the leaves, do you think this ?
Other views from different directions don't show this (even though still a little overexposed, but there is a lot of white on the property !), so think that is what's happened there.
