"sorry for the noise"? xD
That's not too much noise, compared to many other renders

(It's about the usual amount of noise for a finished render, if you don't count stuff like wyt's insane 200h render

)
as a first test, it's very nice

slightly lower the saturation of the two spheres, I'd say... Else, I wait, until you improved what you posted, above
Very well done: you beveled your table's edges
One thing, which is very common to new users: your table legs have normal smoothing problems. Use the edgesplit-modifier to solve those black shadows on the legs

(And do the same for the glass or add some loops, on the upper edge, as there also are smoothing errors)
Indigo doesn't like peaky things (where 90° already is a peak xD)

the standard settings of "30° split angle" in the edgesplit modifier, should be pretty much correct
