I very much like the tone and mood of this image. I somewhat agree with Randy, but might go farther to suggest that it might have been more striking if rather than framing it, the outside edges had been burned in so that the hallway disappeared into darkness.
This is really a great image Tomasz, tones and exposure really combine here, along with the sunlit curtains to create a rather striking statement. I see your title even includes mention of the frame, which I like, but I think the photo gets lost in it. I added one thin pinstripe around picture before adding frame and think it helps the overall look. Nice work.
