This model should ideally make portraits based on the ones you get in missions in Tropico 4 through 6. I don't know what else it can do, but that's certainly a thing it does. By default it seems to color the stuff in, so maybe add "monochrome" or "sepia" as a tag if you want it not to be all colored in. Do basically whatever with it, as long as it's not for profit, I guess.
