Square Image Featuring a Celestial-inspired Mechanical Bird

Create a square image featuring a celestial-inspired mechanical bird as the central focus, perched elegantly with its head lifted skyward in a proud pose. Its sleek, silver body is adorned with finely detailed engravings of constellations that emit a soft glow when the bird moves. The bird's sharp metallic beak is slightly ajar, revealing edges of prismatic glass that catch and refract light into delicate rainbow-like patterns. Its tail is composed of overlapping titanium plates with a brushed finish, while the other feathers are made from an opalescent material that shimmers with iridescent tones. Its eyes, made of glowing sapphires, emit a gentle yet vibrant radiance, offering a striking contrast to its otherwise metallic physique. Along its silver surface, an elegant and glowing inscription reads "a-v-i-a" in lowercase letters, delicately separated by dashes. The background is cosmic-themed with ample negative space, enriched by faint trails of stardust to evoke a feeling of wonder. The overall design should be breathtakingly futuristic yet timeless, with an emphasis on intricate details, high-definition textures, and brilliant luminosity. The visual impact should be awe-inspiring and radiant.
