Generate a digital art image of shepherds, of varying descents such as Caucasian, Hispanic, Black, Middle-Eastern and South Asian, based on the scene from Luke 2:8-9 in the Bible. They should be living in the fields nearby, keeping watch over their flocks in the night. The image should depict the angel of the Lord appearing to them with the glory of the Lord shining around them, and their reactions showing that they were terrified.
