Do angels have faces? It depends on whom you ask, and this is a good window into some practical challenges in prompt engineering ...
In this video, I walk through an example involving OpenAI's text-to-image generative AI model Dall-E 2 that went badly. I am guessing that I got a blend here of the modern folkloric angel, which has a (usually attractive) human face, and the Old Testament angels that more resemble gyroscopes. The point here is that there can be subtlety in surprising places, like whether you would like your angel to have a human face or not, and getting these things right can require knowledge from weird corners.
