AI Prompt for Retro Flip Phone Group Photo Illustration

"Using REFERENCE_1 as the base object and style reference, create a clean standalone illustration of the open Japanese flip phone, removing the surrounding infographic layout, captions, detail panels, borders, and all printed text. Replace the phone's screen content with the group photo from REFERENCE_0, fitted naturally inside the display as if it is being viewed in the phone gallery. Preserve the old silver-blue clamshell phone's angle, keypad, hinge, translucent worn plastic texture, small scratches, and blue star charm strap from REFERENCE_1. Keep the image in the same soft watercolor/anime concept-art style with a pale white background, faint blue shadows, and a few drifting translucent petals. The screen should show exactly 4 people from the group photo: blue-haired girl, black-haired boy, brown-haired girl, and brown-haired boy. Do not add UI text, labels, borders, page decorations, or extra objects beyond the phone, charm, subtle shadow, and petals. Optional customization: use {argument name="screen photo" default="the four-person summer group photo from REFERENCE_0"} on the phone display, with the phone model/color remaining {argument name="phone color" default="silver-blue translucent flip phone"}."
