Shadow Creature in a 1920s Cartoon Speakeasy

Cartoon-style illustration set in a smoky 1920s speakeasy. A friendly shadow creature, an amorphous black silhouette with big glowing cartoon eyes and a cheeky grin, floats above a cluttered bar. Its edges shimmer with a faint blue-purple glow. The room is bathed in warm amber gaslight; cigarette smoke swirls into rings around flapper dresses and pinstripe suits with fedoras. A grand piano with a jazzy pianist, a brass band corner, and Art Deco signage glow faintly in the background. The scene uses bold black outlines, flat cel-shaded colors, and a retro palette to create a whimsical noir vibe.
