Eventually, along with Ahura Mazda, there is Vohu Manah, who usually manifests herself to the Saoshyants, from Ziragšabdar to Acélus ¹. Here is possibly how her initial appearance to Ziragšabdar would have been depicted, hence the stylized stars. These shrubs in the ground are supposed to be haoma.
 
Of course, since Bonnie is Mazda, Manah would be Faust. As for the dress, the lower dress is a practically-transparent pegasus open-back dress, with a smaller sleeveless dress over it.
 
Less than one day to complete this.
