Here's a breakdown of the scene:
A woman in a pink shirt is seen through a brightly lit mirror, standing behind another woman who is seated and has had her makeup done. The woman in pink is smiling and brushing the seated woman's hair, which is pulled back. Several makeup brushes are in containers in the foreground, in front of the mirror. The room appears to be a makeup studio or dressing room, with multiple mirrors and professional lighting. The woman in pink pauses brushing the woman's hair to take a selfie with her phone.
