I like one better than two but I think it could use some work. Maybe make the body's background or the nav bars slightly lighter than the other and push the glow or a drop shadow to add some more depth to it. slight gradient as the bg or a dark solid or gradient with a tileable or faded tileable pattern. Put a drop shadow on the body.
Lol, since you have them both built already why don't you write a script that shows the one with the office themed one (pinned up polaroids on cork board) during standard work times and the other one after hours. Since they have different content in them, if the same guy checks it multiple times throughout the day, they get a different tour that could possibly push them towards taking that final step.
I noticed some of the preview movies open up the preview in a new page. Pimproll has a few sexy tours that have the flash player play on click instead of going to a page. Here is an example,

Warning! I am a nobody in this biz. Just tossing around a few ideas that initially came to me when I opened up the links. Sorry if my ideas actually suck, I tried lol!
Best of luck!
