Sun goddess portrait, close-up with highly detailed skin, looking at the viewer, featuring stunning gradient colors, with a heavenly and detailed background. The composition should have no watermark or signature, showcasing an insanely detailed face with earrings and subtle smudges on the skin to add realism. Capturing a serene expression with a closed mouth, the image should present a vibrant and ethereal atmosphere, incorporating HDR effects without any text, trademarks, or artist identifiers. The depiction shows a unique blend of celestial and natural elements, with particular emphasis on exquisite detail, portrayed against a luminous setting.
