A horizontal garland of realistic hanging seashells strung on a thin natural cord, stretched across the top of the frame like a beachy banner. Each seashell is painted or carved with a letter, collectively spelling out 'HGB'. The seashells vary slightly in size and texture for an organic look. The background is solid chroma key green for easy green screen removal. Lighting is soft and even, with shadows kept minimal to ensure clean compositing. The overall aesthetic is coastal, tropical, and clean — perfect for overlaying on a livestream.
