Create a haunting anime 2.5D portrait of the Hollow King, a once-noble ruler now consumed by darkness and greed, as he kneels before the Dark Lord, who is a humanoid figure made entirely of shadow. The Dark Lord, though the size of a normal man, exudes an overwhelming presence as he stands in front of the Hollow King, his form indistinct and made of swirling shadows, with only his piercing red eyes clearly visible, glowing with malevolence. The Hollow King, with his gaunt, hollow face, long dark hair flowing down as he bows his head in submission, and piercing red eyes dimmed in acknowledgment of his subservience, kneels in his dark, regal robes. The robes are intricately embroidered with golden patterns, though now tainted by the dark energy that has overtaken him. His elaborate crown sits upon his head, tilted slightly as he kneels, reflecting his fall from power. The throne room is dimly lit by flickering braziers that burn with a sinister red fire, casting long, eerie shadows across the stone floor. The Hollow King's fallen honor guards stand silently along the walls, their eyes glowing faintly, watching as their master submits to the Dark Lord's will. The pillars that line the hall further enhance the sense of foreboding, framing the scene of the Hollow King's submission. The composition should emphasize the power dynamic between the Hollow King and the Dark Lord, capturing the king's kneeling posture and the commanding, shadowy presence of the Dark Lord. The dark lord's shadowy form should be subtly detailed, with swirling shadows that suggest a humanoid figure, while his glowing red eyes remain the focal point. Incorporate zentangle pointillism watercolor with a soft pastel touch to bring out the intricate details of the scene. Techniques like sgraffito, sfumato, and chiaroscuro should be employed to create depth and a moody, oppressive atmosphere. The overall aesthetic should blend elements of fauvism and expressionism to create a powerful, emotionally charged image reminiscent of a highly detailed Japanese animation still.
