Need help color scheme

Ti

Something feels off about this and the color scheme, but I cant put my finger on it. My husband wants me to change the carpet to something more neutral (so you would see the walldecal better), but I just feel with or without the carpet something is off. I wish I had neutral colors for the curtains but these were installed 2 years ago, I also wish the furniture wasnt all white but it is all hand-me-downs so I didnt get to choose really but am just very grateful for receiving them. The brown thing on the right is my bath so that will not be there in the future. All tips are welcome!
