Lovely work!
Things that got my attention:
- let it cook longer. There is a lot of noise that vanishes if you just wait more.
- the chrome of the table seems too mirror-ish. What IOR do you use? I would not go over 30.
- if you want that shelf to look arranged then you have to fill it with more objects. You make yourself a hard time if you put shelves that big. ;)
- I doubt that anyone would put the clock on that height. My opinion though.
Anyways, good renderings!
