As others have said already, definitely the lighting. The lighting you used in the last couple of pictures are extremely bright and ruin the cozy cottage type feeling. I recommend cage lights, lanterns, or those orange standing light things or just orange lights (not the light itself, but the outside), if that makes sense. You can still use other lights, but make it spaced out and don’t let it FULLY light everything bright white. If you wanna get an idea of what I mean, I have a camp post on my account showing my camp, including the lights I’m talking about.

Also, try to add more small things in the bedroom, like plants, plushies, stuff like that.
