yes i agree about the crop, a wider crop would show more of what the person is looking out to, via the reflection on the window, although interesting shot...
I think I would've liked it better with a polarizer to block the reflection in the left window. It would be great to see two different booths of the resteraunt.
I really like the idea and the corner view. I agree that that the crop is a little tight. And, like Jadin, I'd rather not see the reflections of the cars, but maybe that tension (person vs. cars) was part of what you were after.
