Pastel Height Difference Best Friends

Goal: Create a nostalgic pastel Japanese height-difference comparison illustration for two best friends, with a central measuring ruler and cute profile poses.

Canvas: Vertical portrait image, soft pale pink paper-textured background, delicate brown line art, watercolor/anime fashion illustration style, gentle vintage stationery aesthetic. Add a faint small “Ai” mark in the upper-left corner.

Layout: Center a tall decorative height ruler from 0 cm to 200 cm, topped with the vertical Japanese title 「身長計」. Place exactly 2 full-body girls in side profile facing each other: the shorter girl on the left and the taller girl on the right. Draw dashed horizontal guide lines from each girl’s head to the ruler. Add exactly 2 ornate name-and-height cards near the top, one left and one right. Add exactly 2 cloud-shaped thought bubbles near the lower sides, one for each girl. Add a small bottom plaque centered under the ruler.

Central height ruler details: A narrow cream-colored vertical ruler with ornate corners and thin brown border. Mark every 10 cm from 0 cm to 200 cm with labels: 0 cm, 10 cm, 20 cm, 30 cm, 40 cm, 50 cm, 60 cm, 70 cm, 80 cm, 90 cm, 100 cm, 110 cm, 120 cm, 130 cm, 140 cm, 150 cm, 160 cm, 165 cm, 170 cm, 180 cm, 190 cm, 200 cm. Include small tick marks between labels. The shorter girl’s dashed line aligns at 150 cm, and the taller girl’s dashed line aligns at 160 cm.

Left character: A petite girl named [left character name], height [left character height]. She stands in profile facing right, hands relaxed at her sides, wearing a white short-sleeve blouse under a dark blue denim overall dress, loose white socks, and black high-top sneakers. She has long dark brown hair in a high ponytail with soft strands and a small scrunchie. Her face is intentionally obscured with a soft square blur.

Right character: A taller girl named [right character name], height [right character height]. She stands in profile facing left with a relaxed posture, hands in pockets, wearing an oversized beige knit sweater, loose faded blue jeans, and black-and-white low-top sneakers. She has long dark brown hair tied in a high ponytail with wispy bangs and flowing strands. Her face is intentionally obscured with a soft square blur.

Text content: Use Japanese text exactly as visible. Left top card has “Name”, 「ひな」, “Height”, “150cm”. Right top card has “Name”, 「あおい」, “Height”, “160cm”. Left thought bubble says 「あおい、まだ背が伸びた？羨ましいな…」. Right thought bubble says 「ひなはこのままで可愛いよ♡」. Bottom plaque says [relationship label], with a small heart icon on each side.

Style constraints: Keep the illustration delicate, soft, and feminine; use muted browns for outlines and text, cream panels, and pastel pink background. Maintain clean readable typography with a Japanese serif feel. Do not add extra characters, extra cards, extra speech bubbles, or additional decorative objects beyond the hearts and simple ornamental borders.
