High-resolution semi-realistic anime illustration, crisp black outlines, expressive shading, rich natural lighting. A young woman balances on the slanted railing of a half-sunken wooden shipwreck, her bare feet gripping the damp, weathered planks as gentle waves lap against the hull. Her long, auburn hair is styled into loose, messy twin braids, a few strands sticking to her sun-kissed skin from the ocean breeze. She wears a cropped, off-shoulder top with delicate lace trim, paired with high-waisted linen shorts, the fabric slightly damp from the misty air. Her sharp, amber eyes glimmer with curiosity and quiet nostalgia as she gazes toward the open sea, the golden hues of the setting sun reflecting off the rippling water. Around her, rusted metal beams and broken wooden masts protrude from the wreck, tangled with seaweed and barnacles. Distant seabirds cry overhead, silhouetted against the warm glow of the sky, while the vast ocean stretches endlessly toward the horizon. Painterly deep blues, sunlit golds, and muted teals create a serene, melancholic yet adventurous atmosphere.
