Chibi Witch Halloween Mobile Poster

Vertical 9:16 Halloween mobile poster, stylized 3D cartoon illustration. [Colors] Deep indigo (#2A1C6B) to violet (#5B3A9E) night gradient, warm gold moon (#FFD27A), pumpkin orange (#F07C1E) with glowing amber interior (#FFB43C), dusty mauve foreground (#7A5A72). [Layout] The top third holds stacked headline blocks with a small caps kicker; the center is a single hero vignette of a girl perched on a pumpkin; the bottom fifth carries a date pill and two closing lines beneath a soft glow. [Typography] Rounded, glossy candy-like display type with a cream fill, deep plum outline and faint inner glow; a small letterspaced "HAPPY HALLOWEEN" above; an italic numerals date; a soft white rounded sans for the closing lines. [Subject] A chibi witch girl in a burgundy dress and oversized pointed hat sits atop a huge carved jack-o'-lantern, raising a star-tipped wand; a black cat with round yellow eyes perches beside her, one paw lifted. [Lighting & Mood] Warm rim light spilling from the pumpkin cut-outs, magical, cozy and mischievous. [Details] Distant castle with lit windows, full moon, circling bats, weathered wooden fence, scattered gourds and fallen leaves, soft volumetric haze, fine grain.
