Diverisity Issue
I have started using your model as I like the face rendering and other bodily accuracy.
But I have noticed an issue. These 4 images were created from the prompt "A group of service engineers in orange overalls and white hard hats, wearing eye protection, standing round a table on which are laid out engineering drawings. The background is a large industrial plant"
Ignoring, for the moment, the absence of a table in three of the four, and that bare arms don't go with overalls, the more concering issue is that all of the people portrayed are White. And Male.
Now, this may be an artifact of the training set, where the description 'service engineer' is poorly represented. But that just pushes the problem back one place. People of any skin colour and gender can be service engineers. We must represent that.
