Thoughts:
I wish they were a little higher resolution.
The loading bar isn't center but in a less obtrusive place.
Your server was faster for the US. It's awful slow from here.
The mousewheel worked. I guess this is to do with the iframe.
There was sound.
You could change scenes from within krpano without going back to the map.
I love the intro page. That could have been done in krpano as well and built into a scene so the whole project was connected.
Cool project!
