文字なしのかわいいハロウィンのスマホ壁紙で、やわらかな光を添えた夢のようなフラットイラストです。石垣の上で光るジャック・オ・ランタンのまわりを、笑顔のおばけ3匹が漂い、紫の夜空にはお化け屋敷、コウモリ、クリーム色の大きな月が見えます。まだ文字は入っていないので、空の空いた部分に自分の名前、あいさつ、日付を入れて作り直せます。

Create a finished vertical 9:16 Halloween phone wallpaper, with no text, lettering, phone frame, clock, widgets, or icons. Use a soft lavender-purple night sky with a gentle tonal gradient and sparse pinprick stars. Keep the top 28% calm, open, and low-detail for a phone clock: only smooth purple sky and a few faint stars there. Place the main illustration in the lower half, with small friendly white ghosts, rounded pumpkin-orange jack-o’-lanterns, and tiny dark-violet bats floating at varied heights. Give each ghost a simple readable face and a softly glowing edge; pumpkins have warm candlelit eyes and mouths, not frightening expressions. Use rounded, hand-cut paper shapes with subtle matte-paper grain, soft ambient shadows, restrained orange and mint-green accents, and diffuse moonlit lavender illumination. Keep the silhouettes crisp and recognizable at phone-thumbnail size. Scatter a few tiny starbursts and wisps of translucent lilac cloud around the lower motifs, leaving generous breathing room between them. Cute family-friendly Halloween, no gore, no dense detail, no bright hotspots in the clock area. Full-bleed wallpaper artwork.
