For some reason the light of your windows made me think of a french-ish type of room. You could do hot pink, white, and black as a theme. If you focus on whites for your walls, you can maintain a wide open feel that won't make you feel closed in (despite those great windows)

Do one wall with toile wall paper in black and white. Paint the other walls white. There are so many whites you can choose, but a crisp, snow white is the best.

To bring in hot pink, add a large area rug to your floor. An area rug such as this hot pink flokati area rug would contrast beautifully with the lightness of your room.

Once you've picked your wall colors, focus on accents to bring your room together. With white on the walls, you can have bright bedding. A white/pink pattern would be perfect, with pink throw pillows. Your black furniture would look great with a combination like this.
