The Stable Diffusion 1.5 have been trained in some images of Emilia Clarke so If you use the actress name this can boost her accuracy, but if doesn't work just remove, also I recommend use game of thrones in the positive prompt.

I also recomend use wide-angle in negative prompt if you getting too skinny faces.

Recomended CFG scale at 9 or 10. But all depends on wich engine, sampler and model you are using.

Don't forget to do your due prompt work.
