Nine-grid portrait collage with graffiti AI Image Prompt

A nine-grid portrait photography collage, with the person consistent with the reference image, showing a figure wearing a loose sweatshirt with the word 'autumn' printed on it and carrying a bag, in various outdoor poses, with backgrounds such as streets and trees.
