Depict a scene inspired by Exodus 15:20-21. Show a woman, identified as a prophet and a sister of a man, holding a tambourine and leading a group of variously descended and gendered people, also with tambourines, in a dance. In the background, create an illustration of a song narrative about a triumph over adversaries, symbolized by a horse and rider being swept into the sea. The entire representation should be in a synthetic, pixelated style, reminiscent of the 21st-century digital art era.
