OBdonman, Create a portrait of a teenage girl with long, flowing, raven-black hair interwoven with strands of shimmering silver. Her eyes, a deep shade of violet, hold a wisdom that belies her age. She wears a flowing, gothic-inspired gown of deep purple velvet, adorned with intricate silver embroidery. A single, black raven perches on her shoulder, its obsidian eyes mirroring her own. The background is a dimly lit, gothic cathedral, its stained-glass windows casting colorful patterns on the stone floor. The style should be dark and atmospheric, capturing the girl's mysterious aura and the grandeur of the cathedral. Focus on a contemplative and enigmatic expression, a young woman with secrets yet to be revealed.
