Well done. The second and third images are looking good in my opinion (I believe the first image would look good too, if you would use a shadowmap like in the other 2 images). I like the warm mood in the rooms. But Im not sure about the shadows. In the second Image you can see 2 shadows from the table left and right, but no shadow under the table... Maye some more lights could help making the shadows more realistic. But all in all it looks good to me.
