AllMusic editor Michael Gallucci found that "on her second album, [Price] goes through many R&B motions – over-singing, pallid bedroom songs, tuneless tales – but still manages to sound like a genuinely thrilled diva in the process.

Filled with slow jams, slick hip-hop, and gospel, Mirror Mirror is a more rounded record than Price's debut [...] She puts an individualist's stamp on the album, a looking glass, if you will, into her soul.
