Fantastic job here! My biggest recommendation is try using some multires sculpting on the pillows and cushions to soften them and give them a more realistic look. Check out some reference photos to see how they’re formed.
And just a note about scenes like this in general… One thing a lot of interior scenes in particular suffer with is that so many feel “stiff” and “stale” and almost like a “showroom” model because they lack certain details. It’s great that you have the sculpt, the plants, and the lamps, but think about who lives in this room. Are they married? Single? Have kids? What interests do they have? Hobbies? Do they like to read? If so, what kind of books or magazines? Are they neat and tidy or lazy and messy? All of these can help inform what kinds of things you might want to put into a room like this and will make the resulting scene more visually appealing and interesting.
Most importantly, add imperfection! Using multires to sculpt wrinkles will help, but so will changing the rotation of the tables (and anything that’s not a “perfect” circle that gets put on them) even by 1 to 5 degrees. Pull one or two of a stack or line of objects just slightly out of alignment — even for a “tidy” appearance. Remember, nothing in realitiy is “perfectly” placed, so adding these imperfections of placement and rotation go a long way to helping a scene feel more realistic.
What you have here is great, and is a great start! Keep pushing it, and you can turn it into something amazing!
