宮殿の庭園を優雅に歩く若いプリンセス

9:16 vertical medium shot of young Spanish crown princess, wavy ash-blonde hair loose to shoulders, blue eyes smiling subtly, in pastel blue silk midi dress with boat neckline, pearl belt and drop earrings, wide-brim hat held in hand, walking gracefully in palace gardens with manicured hedges and fountains, soft golden hour sunlight filtering through leaves creating dappled light on fabric texture, natural depth of field at 50mm, photorealistic 8K fresh royal elegance.
