Live Flyer Variation Generator

Maintain this character and art style, and generate various {argument name="theme" default="live performance announcement flyers with different outfits and poses"} split into a 2x2 grid, looking like it was created by a professional designer.

Feel free to conceptualize the outfits, poses, music genres, backgrounds, lighting, and flyer designs, giving each of the four a distinct appeal and unpredictability. Incorporate visuals that convey the excitement and worldview of a live performance along with striking typography, and include fictional announcement information such as concert titles, dates, and venues for a professional-grade finish.

Maintain the exact same character and the exact same art style across all four. The overall aspect ratio should be 4:3.
