Portrait poster, dreamy, gentle

Use the user-uploaded portrait as the sole character identity reference to generate a standalone vertical music poster. Adult woman, long black hair, wearing a blue small flower hair clip, a light blue knit cardigan and a white lace dress, holding a white or ice blue electric guitar. Preserve the character's natural and realistic facial features and skin texture, with a gentle, dreamy expression, slightly emotional, and a relaxed natural pose, not stiff, not deliberately provocative.
