Detailed Image of a Celestial-themed Mechanical Bird

Create a detailed image of a celestial-themed mechanical bird featuring a gleaming silver body adorned with intricate engravings of stars and constellations. Its mechanical beak, slightly ajar, reveals an illuminated quartz core within that gently pulses with a soft white glow. The edges of the beak, sleek and polished, mimic the shape of crescent moons. Its wings are crafted from overlapping metal plates that shift between vibrant hues of deep blue, purple, and green depending on how the light strikes them. The bird's tail feathers are elongated and graceful, composed of delicate filigree patterns resembling constellations scattered across the night sky. The bird’s eyes are radiant opals filled with swirling motions that create a captivating interplay of light and shadow. Etched onto its chest is the text "st-arl-ing," written in all lowercase letters with precise dashes, perfectly complementing its celestial design. Position the bird centrally within a rectangular frame, its head facing forward and wings slightly extended in an elegant pose. Above and below the bird, leave ample space for a nebula-inspired backdrop composed of soft gradients blending indigo, violet, and shimmering silver sparkles. The overall aesthetic should convey an ethereal, otherworldly charm with meticulous high-definition detailing and an enchanting allure. Ensure the image is visually striking while avoiding excessive brightness.
