Create a visually captivating motion poster for a romantic love song. The background features a dreamy sunset or a moonlit night with soft, glowing lights. In the center, a couple stands close, silhouetted against the scenery, exuding warmth and deep emotions. The title of the song appears in elegant, flowing typography, softly illuminated. Gentle motion effects, like drifting petals, floating hearts, or subtle sparkles, enhance the romantic feel. The color palette consists of warm tones—soft pinks, deep reds, and golden hues. The mood is emotional, intimate, and cinematic, with a sense of longing and love.
