Velma Dinkley in a provocative academic-inspired outfit, showcasing her curvy figure and intricate tattoos, amidst a minimalist backdrop with a faintly visible chalkboard and scattered puzzle pieces, rendered in a vibrant, ultra-realistic 4K image style reminiscent of Niji3D's artwork, with visible JPEG artifacts, a signature, and a watermark bearing the artist's username, displaying a cropped, low-resolution, and blurry representation of the illustration, while an extra hand discreetly lingers in the background, wearing a surgical mask, with the title "The Mystery of the Missing Data" emblazoned across the top in bold, elegant font, and the artist's trademark at the bottom, alongside a logo for the fictional "Sleuth's Guild".
