Added textures to it. Also in addition, I tried to make the carpet look more like a carpet as it looked kinda flat. The same for the walls sort of. What I did for it is to look like it's wallpaper. I don't think that went well, so I am going to try many things to get it to look more like what I am aiming for it to look more of.
I took the light coming out of the window off so you can see the textures better.
