You don't seem to have gained much benefit from using HDR. The sky in the window is all blown out.

What is the exposure range in stops?

-2 0 +2

Actually I think it's kind of funny that they sky looks quite dramatic in the reflection in the glass doors.

Have another go, and try using four or five shots, and with a wider bracket range. Keep in mind what you're trying to accomplish with an image, though, as HDR shots tend to have a very fantasy-like look to them, which may or may not be desirable.
