这是一幅万圣节角色插画，画中是双头南瓜怪，没有标题文字，采用有光泽的3D卡通风格。一个发光的南瓜灯头和一个睁大眼睛的头，长在带有糖玉米的紫绿拼布身体上，背景是月光下的墓地。你可以加上自己的标题、日期、地点以及嘉宾姓名或装扮文字，把它改成派对邀请函或海报。

Create a finished square Halloween character illustration: one bizarre, very fun, vividly colorful two-headed creature with substantial sculptural 3D depth. Make the character the unmistakable hero, filling about 78% of the frame and staying comfortably inside the edges. Give it one compact, wobbly body with two distinct oversized jack-o’-lantern heads growing from the same shoulders: one head grins with asymmetrical triangle eyes, the other has a comically startled expression with round mismatched eyes. Make the heads feel like a peculiar pair, not a duplicated face. Use chunky rounded, glyph-like sculptural shapes in the body and limbs, with playful uneven proportions, short bent arms, tiny pointed boots, and a few harmless candy-corn details. The forms should have clear, readable silhouettes and dimensional bevels, not resemble any readable letters or words. Treat the heads as ridged orange pumpkin rind with thick, slightly rough carved edges and warm candlelight glowing from inside the facial openings. Add small, glossy slime-green drips at a few edges, spooky-purple clothing accents, and delicate spiderweb threads between the heads and shoulders. Use a bright pumpkin-orange, slime-green, and purple palette against a deep midnight-violet Halloween night. A soft warm glow from the pumpkin faces gives the creature dimensional highlights; cool purple moonlight rims its outer silhouette. Keep the background secondary and uncluttered: a pale full moon, a few tiny bats, low drifting fog, and distant crooked tombstone and bare-tree silhouettes. Cheerful, oddball, friendly-spooky, never frightening; no blood, gore, horror details, text, lettering, labels, or extra characters. Crisp focal silhouette, rich color, tactile surfaces, and clear separation between foreground creature and night background.
