It's probably just a matter of the point of view ;-))
I love the flight I can drive myself over Manhattan (thanks to you as a photographer and to Photosynth); but the first one was better (I found it better!) I tried to have a view over the Chrisler building but could'nt find it; if you 're going to fly again, please ...
Ok, it's funny to move the point cloud and see the building from floor level, and how high it is. I'm not sure, but it could be better if you crop closer to the building (different subject but have a look on how close I cropped around the statue http://photosynth.net/view.aspx?cid=8a0bd4ed-6dbd-4f93-8084-962b53deecb6 )
But there is a risk: sometimes you believe the program is synthing with the main subject, but it does'nt even notice it and synth only with the background; it's dangerous with your ESB because the 4 sides are nearly the same; good luck!
