1: Compositionally, never show the back of a chair. Stand closer, make a welcoming stage set rather than standing back in a dark cavern. Remove visual barriers to our engagement of the scene.
2: Overall dark scene [even if you intend it to be so] needs more golden ambient light or general brighteners.
3: Move camera VP to right and rotate to the left to get more window in the shot. VP higher.
4: curtains need more gossamer softness to not look like draping sheet metal
5: Etc.
