It is not a mistake in the arrangement but the purchase. Make sure the furniture is proportional to the size of your room. The enormous solid sofa can be comfortable, but if it is the only thing that fits in the room, it is not proportional, making it impossible to get a well-arranged and balanced room. The same is valid for the heights of the furniture. If you have a greater wall height, the space will automatically look more significant, and you can have taller and more massive furniture. Another point is that a large sofa and a small side table will also look disproportionate, so think about how to arrange your home comfortably and achieve synchronicity, even when buying or deciding which furniture to place in your room!
