It feels like there is some depth of field going on here, but not enough to give me focus close, yet things seem out of focus in the background.
I cant really tell the texture of the stairs or the back wall, so I might add something to that. I also might change the pots to be some dramatic color to give the room more interest.
This angle is also an odd choice. My focus is going towards a wire chair which just isnt that interesting to me. Am i supposed to focus on the architecture or chair?
Lighting looks great and some of the textures as well. Some tweaks and this can really stand out. I like this site for reference: http://www.greatbuildings.com/
