You've gotten me confused about what you're going for. I figure the goal is "this is what this would look like, if there were a person with a balloon for a head and we captured him with a video camera". The linked video isn't there yet, but it seems obvious what would or wouldn't make it good, and the list of traits you describe is really all I want in an image generator. I don't care what the girl is thinking about; that doesn't show up in the image anyway. I do want to be able to say "no, make the hair shorter", or "turn her to face more toward the left of the frame" or "have her pointing at the door in the background". If that command takes the form of a comma-delimited list of traits, so what?
