hi hope you like c&c Welcome
Nice images and an interesting interior .
The only thing i would change is the leather material on bed , looks too rough.
Maybe lower bump value would help.
- Fix the bed cover UV’s and that black thing on top of it. Also bed cover is like 0 bump? Could it be done something to it?
- Lamp shade transparency is weird. Is it intentional to see light bulb? I expect it to be barely visible and have no sharp edges.
- Does black elements material on square column changes from render to render? It does feel like two different to me.
- Ceiling is pretty “busy” but it’s is only my feeling.
- Second render “begging” for more light sources rather just portals. It does feel pretty dead for now.
Otherwise you getting there 
Looks good. What are you using for lighting?
That.
It covers all, but also your leather cells are quite large. Its like elephant skin or crocodile scales.
If you need some hints on how to make a nice lamp shade that you can control nicely with almost no noise, feel free to pm.
