A realistic illustration of a single isolated floor tile with a slight angle that showcases its volume. The tile should be shaped like a promotional burst, similar to those found on sale items in grocery stores. Incorporate a marble texture into the illustration for added realism. Focus on capturing the details of the tile's surface and the play of light on its three-dimensional form. Ensure that the promotional burst shape is clear, and feel free to experiment with angles that enhance the visual impact of the tile.
