This progression is a lot of trial and error and then either using a Character to keep the face or keeping the prompt very similar and/or using the same seed between images. It’s real random chance with the seed if you get something nice or off the wall. I couldn’t get the “green eyes” to not totally change the whole appearance so it ended up as a header image.
