About overall exposure and burn, I prefer the one in your first post.
But IMHO, it looks a bit blurry.
I think the 2nd one is somewhat over burned and 3rd is somewhat under.
I love the bright direct lighting on the bedding in 1st version.
i send anothers two images like the first i have posted but more shrpened to reduce the blurry...
what do you think about? i'm looking for a personal style of rendering a little bit different from the classic iperrealistic render...
That's better; still there's problem with fine details.
For example, check the chandelier - it almost looks like as if it's an oil painting.
That sort of effect usually appears when using denoise filters. If you use those, try playing with their settings or use less of them.
Sorry for the critics, but it's a pity to render an image and then 'kill' it with filters
I generally don't feel good enough to comment on someone else's work but one item is just screaming fix me: in the bedroom scene the mirror blends seamlessly into the floor. I would but a small gap between the two which would be more realistic. Otherwise nice work.
