Nice renders.
The only comment I might share is on floor material. It has dark wide strips representing gaps between tiles. So it needs corresponding up and downs while it is now flat. You might remove those gaps from the texture or you might set the proper bump map to make it more real.
Thanks for your very good comments I agree with you <3 <3 <3 <3 <3 <3 <3 <3 <3 <3 <3 <3 <3
