oh in that case I think you need to make the lights actually emit visible light, and I think the circles are a tad too reflective, maybe lower it a tad bit.
In the second one you have floating chairs, and the fireplace is not really giving off any light, maybe just place a warm lightsource inside there. The wood doesn't seem to have a specular/reflectivity map on it underneath the fireplace,

The lightbulbs hold by the dog statues (really cool btw) does look like they are turned off, wouldn't it be better for the scene if they are emitting light as well ?

The leafs look a bit like plastic, maybe add some SSS or translucency to them ?


the circular tables in the back looks very matte, it might look better with some more reflectivity.
floor texture looks low res to me (the actualy texture not the dirt map) Actually when I look at it the walls on the first image looks quite low res too.
