「Hey Boo」は、クリーム色の背景にステッカー風のかわいいカワイイ調で描かれたハロウィンのスマホ壁紙です。ぷっくりした文字は積み重ねられ、オレンジ・紫・緑でスライムのしずくと太い濃い輪郭があり、笑顔のおばけ、ジャックオーランタン、眠る黒猫、コウモリ、キャンディコーン、星が周りを飾っています。見出しを自分の挨拶や名前に変えて、壁紙やストーリー、パーティー用グラフィックとして作り直せます。

Create a finished 9:16 vertical phone lock-screen wallpaper. Keep the top 23% of the canvas as calm, uninterrupted pale cream negative space for the phone clock; do not draw a clock, numbers, interface, or text there. Center the exact headline “Hey Boo” below that open area, large and instantly readable, in plump, bouncy, slightly wobbly cartoon-Halloween display lettering. Give every letter a thick rounded near-black outline, flat candy-bright fills in pumpkin orange, slime green, and spooky purple, a soft cartoon highlight, a gentle glow, and a couple of cute ooze drips at the base. Keep the lettering playful, friendly, and not scary. Arrange chubby little ghosts, smiling jack-o’-lanterns, and a sleepy black cat as charming die-cut stickers around the outer edges, framing but never covering the words or clock space. Add a few tiny bats, stars, a crescent moon, and candy corn as small supporting stickers. Use simple dot eyes and rosy blush cheeks; each character has a visible white sticker border and smooth flat fills. Set the artwork on a pale cream background with soft peach and lilac accents, soft even flat light, no dramatic shadows, only small gentle highlights, thick rounded outlines, and faint hand-drawn paper grain. Leave generous breathing room around the headline. No extra wording, no border enclosing the full canvas, no photorealism.
