Spooky Enchanted Halloween Castle Night Poster

Vertical 9:16 Halloween castle poster, painterly digital illustration. [Colors] Midnight blue (#1B1F5C) to violet (#4A2C8C) gradient, moon white-gold (#FFF3D0), window amber (#FFC46B), ghost pearl (#F6F1FF), pumpkin orange (#F07C25). [Layout] The wordmark spans the top fifth, a bracket-framed subtitle sits beneath with a divider, the castle and moon fill the middle third, closing copy floats over misty ground, and a thin date line closes the bottom. [Typography] Gothic-flavored gold display "HALLOWEEN" with a small witch hat perched on the final letter; an elegant serif headline in a rose-gold gradient; a small bracketed subline; "TRICK OR TREAT" in letterspaced caps above a divider and date. [Subject] A gothic castle with many slender spires stands on a rocky hill against an enormous full moon, every window lit; nine small cartoon ghosts with soft blue shading drift around it at varying heights; bats wheel above the towers. [Lighting & Mood] Moonlit and misty, gently eerie but friendly, cool blues warmed by window light. [Details] Twisted bare trees flanking the frame, glowing pumpkins in both bottom corners, layered fog banks, sparse stars, soft vignette, visible painterly brushwork.
