I'm doing 3d modeling at the moment so I would be capable of designing my 3 dimensional room with alot of detail. However, one thing i noticed about this site is how long it takes to load each room. It leaves you stuck at the front door while the room loads and all you can do is swing it open and closed. I was patient but I would think that alot of people would be turned of by this and leave the site.
