Compose an image of a magnificent peacock displayed in the artistic form of a wide stained glass window. The peacock should be captured in a dramatic pose, with its tail feathers spread out wide and adorned with a complex pattern of stained glass. Each of the eye-catching feathers should be represented by individual pieces of glass in iridescent shades of blue, green, and gold, designed to sparkle with an inner light. The background should enhance the peacock's grandeur, with a subtle design that allows the bird's colors to remain the focal point. The light should be depicted as streaming through the glass, emphasizing the peacock's natural splendor, in a 16:9 aspect ratio to give a panoramic view.
