这是一对适合万圣节的奇比动漫风情侣头像，画面没有文字。一个穿红里斗篷的奇比吸血鬼男孩和一个戴紫色月亮蝴蝶结帽子的女巫女孩坐在满月下，一起拿着一串发光的蝙蝠灯饰。你可以加入自己的名字或首字母，更换服装或发色，并把两半裁成方形头像。

Create a finished 2:1 landscape image divided into two equal square matching profile pictures, left and right. No text or lettering. Keep each character and their face fully within their own half, centered for a circular profile-picture crop with generous safe margins; do not let any head, face, or body cross the center seam. Left square: an adorable little chibi vampire, two to three heads tall, with a small cape, tiny fangs, oversized glossy eyes with two white highlights, rosy cheeks, and a sweet expression. Right square: an adorable little chibi witch, matching in scale and finish, with a pointed hat, simple robe, oversized glossy eyes with two white highlights, rosy cheeks, and a sweet expression. Both characters turn slightly inward and hold one end of a single delicate string of warm glowing lights shaped unmistakably like a small bat; the bat-shaped strand is the only motif that crosses the center seam, joining the two otherwise complete pictures. Set them on a calm purple Halloween night with a large soft lavender moon, a few tiny stars and floating sparkles, and minimal silhouettes of distant clouds. Keep the background uncluttered so both faces read clearly at small avatar size. Use a unified pastel palette of deep violet, lavender, muted lilac, soft pink blush, and warm golden light. Thick, even, soft dark-brown outlines; flat two-tone cel fills; one gentle shadow beneath each chin and hat or hair; tiny white eye and hair highlights; soft even illumination. Cute, polished chibi sticker-like character art, with no die-cut border, no extra figures, no busy scenery, and no single character stretched across both panels.
