You get one perfect image. You try to recreate it. Different nose. Different energy. Close enough to post, not close enough to build on. So you post anyway. Then again next week.
Over time, your brand looks like it was made by five different people — because in a sense, it was. Five different prompts. Five different random seeds. Five different versions of the same person who doesn't quite exist anywhere.
Your audience can't name what's wrong. But they feel it. And so do you every time you open a blank generation window and start over.
