Cozy? I would paint this room a deep green to make it cozy and the texture of the walls will lend itself to rustic. Bring the beauty of nature, which is the focus point, into the room. I would replace the ceiling light fixtures with matching small ceiling fans, recover the furniture pads to coordinate with the color of the walls, switch the seating so that the settee faces the windows, and between the rocker and the settee, I'd put a small end table with a reading lamp. An indoor/outdoor carpet would anchor that area. Some hanging plants in front of the windows would be a nice touch.
