hmmm some nice work but I think with a few tweaks it could be alot more powerful (well it's an ongoing project so it's got to be worthwhile giving some constructve crits) : -
The computer render and the photographic panorama at the beginning of the movie could be better matched by tweaking levels but mainly by blurring the CGI. It's very sharp - and very CGI - compared to the photography.
Alot of the shots have beziered in and out keyframes and, shown back to back, these give a constant stop-start motion to the edit.
Also the sequence of shots seems a bit disjointed with cuts from one space to another without visual cues showing how they all fit together. I know it's a teaser so the jumps probably can't be helped but shots could be tied together through similar motion, composition and timing - a dolly back from the kitchen could cut to a similar dolly away from the tower externally.. one constant speed tracking shot could cut to another etc..so there's some visual continuity. Some of the interior stuff *almost* works like this already, for instance the piano room and the shot that follows but they're different lengths and speeds at the moment.
And lastly some of the compositions I think could be better, especially internally it sometimes fells a bit cramped - but before I'm accused of being too negative, you only notice the average ones because that straight down shot looks so fantastic
Hope that's helpful
