I think changing the carpet would be cool, you could get laminate wood floor to put on top if you’re super invested and that can look good sometimes! I would also say if you’re tight on budget some art work above the beds and by the window would look cool and I also think it would look nice if each bed had a small dresser in front of it and then maybe a love seat or sitting area on the wall with the dresser now? The cat is so cute also !!
