Pastel Japanese Father's Day Carousel Cover

Cute square Instagram carousel cover graphic in a warm hand-drawn Canva illustration style with Japanese lettering. - Composition & Layout: 1:1 square canvas with a cream/off-white textured paper background, framed by a thin rounded pink inset border. At top center, a stitched pink ribbon banner reads "[育児垢ママへ]". Below it, two lines of large dark brown brush calligraphy read "父の日、" and "まだ早いと思った？". To the right of the headline, a pink-outlined white cloud speech bubble contains the text "6月21日だよ". Underneath, a wide coral-pink rounded pill-shaped badge with subtle radiating accents displays white hand-lettered text: "仕込むなら今がベスト". - Main Illustration: In the bottom center, an adorable squirrel-themed family of three sitting together happily: a squirrel-eared mother in the center with an orange high bun and pink cardigan holding a pink smartphone; a cheerful young girl on the left with pigtails, a pink hairbow, and pink top; and a young child on the right wearing a striped cream-and-yellow shirt with a large fluffy orange squirrel tail. All characters feature rounded faces, rosy cheeks, and joyful expressions. - UI & Bottom Details: At bottom left, a tilted white memo paper held with pink washi tape labeled "memo" in pink with dark brown Japanese text: "育児垢ママ向け" and "投稿スケジュール". Along the bottom center, exactly 10 carousel indicator dots (first dot filled coral pink, the remaining 9 outlined). At bottom right, a coral-pink stitched circular badge displaying the number "[1]" in white. - Decorations & Style: Exactly 8 delicate hand-drawn pink heart and sparkle doodles scattered naturally around the margins. Soft pastel palette: blush pink, coral, warm brown, cream, peach, and soft orange. Colored pencil and watercolor textures, friendly rounded shapes, cozy aesthetic. No photorealism, no harsh shadows, no extraneous text or watermarks.
