This could very easily be mistaken for a photo. Great materials and lighting, and the wrong alignment of the camera adds to the realism.
Could you tell us a bit more about this scene? Very interesting stuff.
What do you want to know? 
Well, pretty basic stuff, like if it is a part from a larger project. Are you doing this professionally, or is it just a hobby? What are the render settings, the light sources etc. I think you get the point.
No larger project just this angle, trying to get better at realism for fun. 
Light-source simple hdri, in my opinion the light doesnt have a big impact
on realism. Cycles is a pathtracer even pure white light should look realistic. Its more
about the feeling/mood that changes but not the realism.
Render-Settings: 5K samples, Clamp 2 , 3200x2134 resolution
There is rlly nothing special in this scene just standard-materials, -render-settings and -light.
It looks quite interesting.
Thank you.
Very nice !
Thanks.
Wow, that looks really like a photo. Or is it a photo and you just want troll us? 
I really like that it is not a fancy new york apartment with furniture worth 100k dollar. It’s just
how normal people live. Amazing work dude!
Its not a photo.
Thank you man.
I think most people would just assume it to be a photo unless somebody warned them otherwise, and even then it’s very hard to tell. Great work!
Thanks.
I featured you on BlenderNation, have a great weekend!
Wow, thank you.
