Generate a realistic artwork of Seiya from the anime Saint Seiya, wearing the Pegasus Cloth and in the Pegasus Meteor Fist pose. Seiya's appearance: short brown hair, blue eyes, determined and courageous expression. He is wearing the Pegasus Cloth, which is predominantly white with blue and gold details, shaped like a winged horse. The pose is the classic Pegasus Meteor Fist, where Seiya crouches with one knee on the ground, the other raised, and clenched fists ready to launch the attack. The background should depict a starry sky, with bright constellations and subtle clouds to create an epic and celestial atmosphere.
