Need Critiques About Scene Layout & Composition.


I am making a corner of a room. A Study Corner to be precise.
My teacher said the 1st layout looked like a closet and she thought I was more like a room than a corner of a room.
So I went home and changed the 1st layout into the 2nd layout (with longer wall and floor and include a roof)

What do you think? which one is better? what can I improve here in terms of layout and composition?
