Inside Outside

I don't know how clearly this image comes out, but I have always been interested in photos of this kind. What I am trying to do is to stand near a lighted window, such that I can see both the outside and a reflection of the inside. This has been difficult to capture well, since either of the 2 views can get blurred, especially if an auto-focus camera is used.
I think this one seems somewhat clear, and you can actually click on the photo to get a bigger view. I will hunt around to see whether I can get another clear image like this one.
