Create a photorealistic detailed image of a close-up portrait of a bald eagle, focusing on its head from a slightly left, downward angle. The eagle's eye is sharp and piercing, colored in deep yellow with a large, dilated black pupil, offering a sense of intensity. Its beak is prominent, curving downward with a sharp point, and is a bright yellow with hints of orange, especially near the tip and around the nostril which is simple and slit-like. The feathers on the head are predominantly white, detailed with subtle grays, giving texture. These feathers are fine and well-defined, especially around the forehead and cheek area, transitioning to slightly rougher, larger feathers on the back of the head. The background is a simple smooth gradient shifting from a warm, dark honey hue at the top to a deepened, shadowy amber at the bottom, enhancing the focus on the eagle's head by providing contrast. This descriptive focus emphasizes the noble and fierce expression of the eagle.
