This is my first attempt on an interior scene.
Rendered in cycles, 2000 samples.
Is there anything I can do to let it look more photo realistic?
Thanks in advance for any comments or critique.
There’s a bit of pattern tiling visible on the low wall at right. You might see if you can address that.
i think you should put some texturing onto the wood. also, add a slight cloud tex to the walls and stuff, no walls are that clean 
i agree with f3l1x the walls should have some type of texture or bump looks kind of dull but the lighting and and modeling is great!
Looks nice, I think you can add some greens to break monotone colors.
- Windows seem to close to the wall with the door and to the wall below them - usually there is some space between surfaces
- Window shades don’t look functional - I think there should be more of them and they should be smaller
- The upper part of the window frame seem to be missing?
- Door frame on the left protrudes out too far
Other than that, good job!
