A decorative banner made of three unique, realistic seashells hanging on a natural string across the top of the frame, each shell organically shaped or naturally carved to resemble one letter in the word 'HGB'. The seashells have intricate texture and detail, blending their natural curves into the shape of each letter, without painted or printed text. The background is solid chroma key green for green screen use. Lighting is soft and cinematic with subtle shadows to highlight the shape of each shell-letter. The overall style is coastal and elegant, perfect for a tropical-themed overlay.
