Nice job! ; I like the way you shot them with the large photos in the background.
I finally did a walkthrough myself this past January having not been through with a camera before - but I was unfortunately in there with a number of people, so I didn't really have the time or desire to set up some nice shots like yours - mine were more 'snapshot' like, with much more pedestrian backdrop.
I'd very much like to try some shots more like yours next time!
