Depict a scene inspired by Matthew 11:16-17. Visualize children of diverse descents such as Caucasian, Hispanic, Black, Middle-Eastern, and South Asian, evenly distributed, sitting in bustling marketplaces of the ancient world. They are engaged in play, with some busily playing flutes while others sing. Despite their earnest performances, their equally diverse playmates do not react. Some of the children are performing a joyful dance tune on their flutes, but the intended audience remains unresponsive, not dancing. Others are singing a mournful dirge, but their counterparts do not show signs of mourning. Compose this scene in the style of digital art.
