Thanks for the comments!
Yes, client was very pleased.
On #4, it just so happens I was using a "soft gold" reflector. It has lines of gold mixed with lines of white. But i have not messed with the white balance.
As per the window... ya... it was kind of a double edged sword. Since I wanted the end user to focus more on the product, i figured it was ok to blow out the windows. If i left them more properly exposed, we would see some pretty ugly stuff out there. Now if there was trees or nice looking buildings or something better to look at, that would be a different story.
I agree about the smile (or lack thereof) in #2.
Thanks again!
