Prompt: A sleek and modern sign featuring the initials \"LU\" in an elegant font, illuminated from within, against a dark background. The sign is made of brushed metal with a glossy finish, creating a reflective surface. The lighting creates a soft glow around the letters, adding depth and dimension to the design. The overall look is minimalist and sophisticated. Negative prompt: Poorly designed sign with sloppy lettering, uneven illumination, and a dull finish. The background is cluttered and distracting, taking away from the focus on the initials. The overall appearance is cheap and unprofessional.
