I haven't used Thea for a while, now I've started again and I'm a bit rusty, can you give me some advice to improve the render?
Thank you!
p.s.
I used the Presto engine, it took 13 minutes at 3840X2160 resolution. I have corrected the image with RawTherapee 5.5.

First tip: Take a look at architectural photography. How they light scenes and how colors look. Contrast and so on. There are several different styles you could aim for. Only looking at 3d renders can easily get you quite far away from reality.

Second tip: The white balance in the first image looks odd. The white walls are pink.

Third tip: The brightest part of an image at day time is the sky and to me it looks odd if the exterior is darker than the interior. A correctly exposed interior will almost always have a blown out exterior (do a Google search and see for your self) if it's not edited in post which leads us back to that it looks unnatural.

Fourth tip: When looking at reference photos also take note of composition and field of view. This is something that really can make an image look real or not.

If we are aiming for "photo real" we should look at photos. The human eye changes the aperture all the time so we don't percieve the exterior as blown out. But when we move the eye to the interior the aperture of the eye changes again and we see the interior as correctly exposed. This is not the case with a camera and a still image.

My two cents.

nice detailing :thumbup:

I was also about to post that third tip, but you beat me to it Pixero ;-)
Maybe something like this image shows the idea?

Thanks for the tips. So my mistakes are not modeling and materials, but color and light balancing and photographic framing, right?

100% highlights and 100% shadows??

That's too much contrast for my liking.
I usually still lower the defaults (80% and 15%) to around 70% and 8%

First thing off the outside looks way too dark and a bit oversaturated, you change this and you'll get some depth to the image straight away. Way too much contrast as well and your AO values are probably too high (turn down or off). Might be too strong so called hidden "portals" and "dome light" values as well as something is killing the internal HDRI light bouncing (if used). Maybe switch the ceiling lights on & turn others sources down. Not sure about black massive shelving as well but that's just me.

I agree, a scene like this should only be illuminated by the sky/HDRI, with no internal lighting. At most I would add an area emitter behind the camera.
