Women wearing a black top and glasses speaking into a blue tipped microphone with another woman beside her writing.
Two shabbily dressed women hold mics as they compete in a rap battle in front of a cheering crowd.
women speaking implies at least two plus one writing so it couldn't be two women to compete
The audience is either a woman writing or a cheering crowd.
If one woman is speaking into a microphone while another woman is writing, then it cannot be claimed that both women hold mics. If one woman is speaking into a microphone while another woman is writing, the women can't be said to be competing in a rap battle.
