This was my first work of architecture, it was made in Blender 2.49 and rendered in Yafaray in mid-2009.
Nice work!
One thing I would criticise though is the background picture. I think you used DoF for the room, but the background image is perfectly clear. This looks a bit unrealistic. Maybe I’m completely wrong, but this was my first impression…
i agree, the background picture is obviously a photo, not sure wether its the lighting, angle or anything else.
Good work on the room though 
In the room is sunset but outside is noon .
Thank you for constructive criticism, I really did not use Dof in the background. Thanks for the tip
rs rs rs, boa obsevação.
