Which model to use?

Hello there, I was wondering if someone could offer some advice about which model to use in my situation I have an image that was generated for apple image playground, this is perfect for my needs and I want to use this single image to generate other images using the same girl that is in the picture I have tried a few image to image models (using Draw Things) but they are not giving me anything close to the same girl in the existing image I want to do this totally off line please but I am willing to use other software (running a MacBook Air) if suggestions are made but I feel it is the model After doing some research Flux 1 was suggested, I uploaded my image, tried to mess about with the settings, trying to give no artist license to the model at all but I got nothing close as I said. My goal is to create a series of images that are for a mock up of a children’s book so that the artist kind of gets the idea, but obviously I need a model that can keep a ‘character’ that is the same girl (or animal) Any help that I can get would be greatly appreciated Thanks
