That looks pretty much realistic already. There’s not many things to criticize.
The bevel in the marble piece looks a bit weird to me, did you apply shade smooth? I dunno, I might be wrong about.
The bump in the wall looks a bit high to me, does it suppose to be that rough?
The bump in the seat is high.
Besides those lil things, I think the camera position is killing the scene, is way to close to kitchen counter and the angle of view is too low. I personally would set the angle of view a little higher, let’s say 42, or 50, and set the camera a little far away. I think that would make the scene a lot more good.
Hi. It’s very nice image. 
Hard to find something to correct. But if you want…
I think stools are too height for that table, not comfortable. And chrome pipes are too masive.
First thing I see is croped painting and ‘ON’ letters.
Maybe floor to flat (no specular, bump), maybe to clear connection between floor and walls - I don’t know, it’s hard, sorry ;). Very good viz.
Nice stools.
I think they’ve something on a strange reflection of the last part of the legs…
Sort of whitish halo.
I was trying to figure out what disturbed me. Found it (or lack of it) - no baseboard on the walls.
Hey @HarKMik,
Here is my critique:
-
I think you did a good job on the materials, they look pretty realistic.
-
Either the bar stools are too big, or the counters are too low. The way it is now, you would hit your knees.
Same for the counter in the back I think.
I’d generally suggest to check the proportions. -
baseboards are missing
-
Composition wise I cant give too much critiqe, since I am myself very unsure in that area
Thanks a lot mate.
P.S. I did forget to smooth the shade.
Appreciate the comments!!
Now that I’m seeing it.
I featured you on BlenderNation, enjoy!
