Less is More
You've heard this before no doubt. There's a reason it holds true. If you select key statement pieces with great detail, and the proper scale, the room or overall house will feel cluttered if you keep adding. It takes away from the clean lines and details of the space. It prevents the observer from knowing what to view. It begins to feel overwhelming, as though it needs to be edited. It creates multiple focal points. Some people even start to feel stressed instead of a sense of calm and relaxation. So when in doubt think less not more. Group like items together, embellish with your favorite pieces, and edit down from there.
