AI Cosplay Expo Cat Girls

Goal: Create a polished 2D anime cosplay promotional poster for {argument name="event name" default="AI COSPLAY EXPO"}, featuring a cute cat-themed fashion mascot character shown as two side-by-side outfit concepts. Canvas: Landscape poster, approximately 4:3 ratio, clean off-white background split vertically down the center. Left half uses warm cream, tan, black, and gold accents; right half uses grayscale monochrome with black accents. Add faint geometric lines, rounded rectangular framing, paw-print motifs, and soft graphic shapes behind the figures. Layout: Two full-body chibi/anime girls occupy the poster, one on each side, both floating in playful dynamic poses. Place the event logo centered at the bottom, overlapping the vertical split: a small black cat silhouette emblem above bold uppercase text reading "AI COSPLAY EXPO", with tiny subtitle text below suggesting an international event and production credit. Keep the logo compact and graphic. Subject details: Use the same cute anime girl concept twice. She has large sleepy eyes, a small smile, curled twin-tail hair, cat-ear headphones or cat-ear hood styling, bows, frills, and a toy-like gothic-lolita cosplay look. Left character: blonde curled twin tails, black cat-ear accessories, leopard-print cat cosplay outfit with paw gloves, leopard tail, black garter details, chunky black platform shoes, small black choker, and warm gold/black decorations. Right character: grayscale silver-haired version with cat-ear hood, oversized blouse sleeves, black pleated skirt, bow tie, thigh-high socks with small motifs, chunky black shoes, and a small round cross-button accessory near the cat ear. Visible repeated elements to include exactly: 2 anime girl character versions; 5 floating cat plush/mascot charms around them: a black cat charm hanging near the upper-left figure, a small black cat at lower left, a pink cat plush near the lower center-left, a gray ghostlike cat plush near the upper right, and a gray cat plush near the lower right; 2 cat-faced handbags or purse charms, one gold round cat purse near the left character and one pale round cat purse labeled "GEEBO" near the right character; 3 visible paw-print graphics near the bottom and background, including one black paw and two golden paw prints. Visual style: High-quality Japanese anime illustration, crisp clean line art, delicate cel shading, glossy eyes, detailed accessories, fashionable cosplay design sheet aesthetic, cute yet slightly gothic, magazine-poster composition, balanced negative space, no photorealism. Constraints: Preserve the vertical warm-color versus grayscale contrast. Do not add extra characters. Keep all visible text minimal except the bottom event title {argument name="headline text" default="AI COSPLAY EXPO"}. Use a clean white/cream background, no watermark, no realistic photography.
