here is a littl room I rendered. its got the bottle I made.
I like the model of the chair, lots of details. The shadows are a bit irritating, window is on the left but chair has shadow falling to the left. Maybe set the light inside the room shadowless.
The table going to the left makes the picture feel cramped i think. If you wanted that effect ok but else I’d move it so it ends before the picture does.
Also the texture of the room walls needs some work, I can hardly see where the corner of the room is.
Where did you put the light that goes in the window? It should be shining from outside the window, by the looks of the curved light path and the bright spot you put it inside the room.
