A professional graphic design presentation sheet showcasing 4 elegant, premium avatar options for an underground club brand named 'CLUV FLASH', displayed side by side on a solid black background. The central icon is a sleek, completely black 3D minimal disco ball sphere detailed with sharp, razor-thin white mirror grid lines. Passing directly through the center of the black sphere, a subtle and glowing neon audio waveform spectrum cuts horizontally across the layout. The club name 'CLUV FLASH' is integrated in an ultra-subtle, tiny, and sophisticated white technical typography in the center, elegantly highlighted by the passage of the musical spectrum. High-end modern clubber branding, clean geometric aesthetics, extreme graphic contrast, high resolution."
