A whimsical yet darkly vibrant scene featuring Harley Quinn as a Jim Henson-style Muppet, striding confidently down a desolate, rain-soaked Gotham City street at night. Her exaggerated Muppet features include wide, expressive eyes with a mischievous glint, a broad, toothy grin exuding both arrogance and charm, and a dynamic, bouncy walk that radiates energy. She wears her iconic red-and-black jester outfit, reimagined with felt textures and bold stitching, complete with a floppy hat and diamond-patterned leggings. Her hyena companion, also a Muppet, trots beside her with a goofy, slightly menacing grin, its fur a patchwork of brown and beige felt. The environment is dark and moody, with cracked pavement, flickering streetlights casting long shadows, and towering, crumbling buildings in the background. The atmosphere is a mix of ominous and playful, with a dynamic composition capturing Harley mid-stride, her arms slightly raised as if leading an unseen audience. The lighting is dramatic, with deep shadows and glowing neon highlights in red and purple tones. The scene is rendered in a hyper-detailed, cinematic style, blending the whimsy of Muppets with the gritty aesthetic of Gotham.
