By the Bronze Age, around 2000 BC, people in northern India were richer, because they were trading more with West Asia and Central Asia. They could afford to build cities. And they could afford to make more expensive art than their Stone Age ancestors at Mehrgahr.
Harappan artists made bronze statuettes (little statues) like this dancing woman. She’s totally Indian. She’s way more of an independent person than any women in West Asian art at this time. They made pottery decorated with painted rows of flowers and animals, like West Asian pottery. They carved small stone statues, too.
