Four Anime School Reference Panels

Goal: Create a 2x2 comparison collage showing four generated anime-style reference images for a short video concept, on a dark charcoal background with large white labels. Canvas: Landscape 3:2 composition, approximately 1200x900 px. Use a matte black/dark gray background. Arrange exactly 4 rectangular image panels in a clean grid with generous margins and gutters. Each panel has a large bold white label above it: exactly 4 labels, “@image1” at top left, “@image2” at top right, “@image3” at bottom left, and “@image4” at bottom right. Overall visual style: Soft hand-drawn anime illustration, warm muted colors, gentle line art, subtle watercolor-like shading, nostalgic Japanese school atmosphere, clean character design, no photorealism. The recurring subject is {argument name="character description" default="a cute middle-school Japanese girl with shoulder-length dark brown wavy hair, simple dot eyes, a small smile, and a sailor-style school uniform"}. Her outfit is consistent across panels: cream short-sleeve sailor blouse with navy trim, orange neckerchief, dark plaid pleated skirt with orange and teal lines, navy knee socks with orange stripes, and beige sneakers. Panel @image1: A single illustration on a warm beige background. Show exactly 1 girl sitting at a classic school desk and chair in side three-quarter view, facing right. She is relaxed with both hands on the desktop as if writing or reading. Include exactly 1 desk and exactly 1 chair, with thin black metal legs and a wooden seat/backrest. Her legs extend forward slightly; sneakers are visible. Keep the background plain and minimal. Panel @image2: A character turnaround sheet on a clean white background. Show exactly 3 full-body views of the same girl, evenly spaced: 1 front view on the left, 1 side profile view in the center facing left, and 1 back view on the right. Keep the proportions chibi-like but not super-deformed, with a large head, small body, and simple facial features. No extra props or text inside this panel. Panel @image3: A bird’s-eye view illustration of {argument name="school setting" default="a small suburban Japanese school"}. Show exactly 1 main school building, rectangular and two stories tall, with a dark teal roof and long rows of windows. Include exactly 1 sandy schoolyard with faint white court markings, exactly 1 perimeter wall, and surrounding residential neighborhood houses, trees, narrow streets, utility poles, and warm afternoon lighting. The perspective should be high aerial/isometric, like a reference image for a 3D scene. Panel @image4: View into a classroom through a large window frame, as if the viewer is outside looking in. In the foreground, show exactly 1 main girl seated at a desk near the window, facing slightly right, with an open book or notebook on her desk. Behind her, show exactly 6 background students seated at separate desks, softly blurred and simplified, facing forward or downward as if studying. Include warm sunlight, window reflections, classroom wall panels, and rows of desks. The window frame should visibly border the panel and create a cinematic shot. Constraints: Keep all 4 panels in the same illustration style and color palette. Do not add extra panels, extra labels, watermarks, captions, or logos beyond the four @image labels. The collage should look like a social media post showing four prompt-generated reference images.
