I’m making this old laboratory as if we were somewhere back in 1920. Maybe this kind of laboratory could still be seen in the 1970s or later depending on the country.
I feel like there’s still a lot of work to do and I’m trying to learn more about realistic light and the video tools.
Here’s how it’s looking so far:
and a video filmed from the viewport:
That is a good start… some shaders need more work (ie: perhaps the roughness map is too smooth for some wood material)…on the other hand, some metal need more reflection (ie: you would have to smooth roughness map, when it points to black)
About the lighting of the entire room: not enough contrast and at this point it is hard to determine where are your light sources.
Keep up! 
Thanks for the comment, I’ve tryed to improve the wood and metal materials. I’ve made some more work and imported more models. Now I really need a floor to replace this generic one. Here’s a couple more pics:
Update. Now with floor and yellow walls.
