Looks ok, a bit sparse at the moment, but as you said more stuff will be added.
Add some sort of wall and floor texture.
I'd use Mentalray for these sort of images with GI and/or Final Gather, the light looks so much more realistic (with less effort).
Also soften those shadows for final render, area lights or something.
The sofa looks nice, a bit plastic highlight, but with some noise to that and a bit of bump it'd look good. The cushions are good, but could perhaps be slightly less noisy (especially since the rest of the sofa is very much straight lines). Lamp, side table and painting looks good. The bigger table looks like it has slightly too thick legs. The book (?) ontop can hardly be seen.
Keep it up. :thumbsup:
