Summer Selfie Sticker Collage

Please use the uploaded portrait as a reference. Create a 2x2 summer selfie collage with a 9:16 vertical aspect ratio, comprising four panels. Ensure that the facial features remain consistent, with soft, youthful features, a warm smile and natural skin texture. In each panel, depict the character outdoors in bright summer sunshine, wearing a straw hat. Have her strike a variety of poses across the four panels: a peace sign selfie, a pose cupping her face with her hands, an OK gesture, and a relaxed close-up selfie. Keep the composition cute, lively and casual. Add colourful, watercolour-style hand-drawn doodles around her: soft outlines around her body and hat, floating soap bubbles, small hearts, simple sun drawings, sparkles, and cute little animal stickers. Ensure the doodles have a playful, hand-drawn feel, like mobile phone photo stickers. Remove all watermarks, logos, AI labels, app labels and signature marks. Keep the decorative handwritten text, but replace it with neat, legible words such as ‘Sheena’, ‘sunny’, ‘cute day’ and ‘summer’. Make ‘happy day’ the most prominent text. Ensure the text looks like colourful, hand-drawn sticker lettering. Style: Soft Korean/Japanese-style summer selfie aesthetic, bright yet subtle sunlight, fresh colours, a slight film-like softness, a refreshing outdoor atmosphere, cute social media collages, clean ultra-high-resolution images. Elements to remove: Watermarks, logos, brand marks, AI labels, signatures, QR codes, random text, illegible characters, misspelled ‘happy day’, long captions, cluttered typography, unnecessary people, duplicate faces within a single panel, distorted faces, asymmetrical eyes, plastic-looking skin, excessively smooth skin, blurry faces, lack of detail, unnatural body proportions, distorted hands, extra fingers, missing fingers, fused fingers, twisted arms, severe overexposure, dull colours, severe compression artefacts, dark and underexposed panels.
