This home is perfect, they have their colors very put together and it creates a warm and relaxing atmosphere. Too much color can be overwhelming and cause more stress after a long work day but these colors cause an auroma of relief and zen.
For a main room I would probably go with bigger chairs, just because these don't seem comfortable. The use of animals is perfect though and the color blend with the books and the blue is sustained very well. The animals add a print and texture that is unique to the room!
