the second is better, it was hard to say something about the first, wich was too "young"
Nice thing that you've put an environment outside
As Mihai said, the floor texture is too repetitive, and work its shader a bit, there are plenty of woods on the mxm gallery wich will help you to learn!
Add bump to the cushions, an add them a more "cloth" shader
Colors of rugs are too much saturated i think, and same, add bump, or use displaced geometry on it!
It seems that plinths have the same shader that walls, apply a more "plastic" one!
The wall corner is too much dark, add light there!
I think you should hide the candles for your next render tests, for rendertime, as they dont really light the scene
Hope it will help
