The generated images are awful, downloadable local models can do a much better job than this.
And then on top of that the entire premise of this website is existentially flawed, either nobody gives a shit about your website and it fades into quick obscurity or it becomes popular and you get sued into the stone age by any and all celebrities whose likeness your model is appropriating (and the agencies that represent them, various creative unions they are part of, etc).
FWIW the former is the actual path this will take because of the low quality of the generated images, so that's actually the best outcome for you.
