My personal current state of art in professional photorealistic ArchViz Blender/Cycles.
Looks good, how did you light it?
I like this very much, the lighting is really nice and crispy. Top notch!
Very nice modelling. The only thing I notice is that the center display case has a kind of curved reflection of the wood floor which looks odd since the surfaces are flat. I’ve found this can happen when using smooth shading; adding edge loops near the edges can help straighten out reflections.
