Overall very nice, very spooky. Terrific flying and camera op at the same time (yes?). What I really like is that you came in from the shade side then showed the sun side during that beautiful golden hour. Only suggestion, flying straight over the top, a little higher and shooting straight down, running the length of the building could have been very nice too. Also impressed that you were able to tilt up so much on that decending shot and not show props. Were you shooting 60p, 30p or 24p?
On a side note, I love how they sealed up the tops of the chimneys but there are big holes in the roofs!
