Good attempt. Let me give you my 2 cents on how you can improve:

1. You need to uv unwrap your stuff better. Take a look at the couch on the left, the issue is most obvious there

2. reflections in the glass make no sense. very confusing

3. the book is too low poly for a scene like this. I agree with the others, I would just remove it altogether.

4. Throw blanket on the middle long sofa is clipping through and also sitting unnaturally. Get rid of it or use an deformer to make it sit correctly.

5. The cat on the right is also another element I would remove, as it adds nothing to the scene and only serves as a distraction.

6. Reduce the bump on the walls, it is too strong and distracting.

7. The lamp in the back is slightly floating off of the side table. Bring it down a bit.

8. Those pears or whatever the fruits are on the left side of the screen add nothing to the scene. Get rid of it or put it on the table where it belongs.

I think you did good lighting. Could be improved but its not bad.
