Ethereal Lavender Birthday Collage Design

Design a vertical birthday greeting card featuring a multi-portait collage with a dreamy aesthetic. Ensure the face from the reference photo serves as the definitive identity anchor, leaving facial structure, complexion, hair texture, and recognizable likeness completely unmodified across every frame. Set the scene against a smooth gradient backdrop transitioning from pale lavender to rich violet. Arrange four distinct, overlapping shots: a prominent smiling bust crop positioned at the uppermost section, accompanied by three compact compositions showing her gazing downward, standing in an empowered posture, and turning her head to the side. Incorporate sophisticated botanical accents, delicate butterflies, gentle light glints, soft-focus background highlights, and high-end cursive script. Maintain an upscale, polished, lifelike editorial style with maximum textural clarity.
