Yesterday I tried to use buckets instead of progressive mode and I love it. )) Almost no noise in few passes. It is easier for me to set only one pass with 10 adaptive steps and i know that end result will bee clean even with DOF
Looks very nice. Especially blue sofa. But there is something strange with reflections in the glass table as for me. I think they must be stronger a lot. Looks like high refractive IOR with dark reflection color.
This is not reflections 
Its table`s construction !
I’m sorry if I do not understand why you are surprised.
I mean reflection of bottle in the glass must be stronger. Just imho.
