An exquisitely crafted and highly detailed 3D watercolor pen masterpiece, featuring a blend of gold, platinum, long color crystals, and gemstones. The central focus is a golden, intricately designed pen with platinum accents, resting on a bed of vibrant crystals. The signature "Buenas Noches Grupo" is elegantly inscribed in beveled gold capital letters, adding a touch of class and sophistication. Beneath the signature, the author's name, "que descansen," is delicately written in the same elegant style. The overall image is a stunning 4K rendering, showcasing the artist's impressive ability to create hyper-realistic, conceptual art with a rich and vivid color palette.
