Create a clean, elegant photo collage arranging all 12 provided full-body female portraits into a neat, symmetrical grid of 3 columns by 4 rows (12 cells total), formatted for A4 paper in vertical/portrait orientation. Place each of the 12 images into its own cell, one photo per cell, keeping every portrait fully visible without cropping heads or feet. Use thin, even white borders (gutters) between all photos and a matching white margin around the whole grid for a minimalist, gallery-like look. All cells the same size, perfectly aligned rows and columns, balanced and harmonious composition. Soft, consistent light gray/neutral studio backgrounds blend gently for a cohesive, aesthetic result. High resolution, print-ready, professional lookbook style.
