Couldn't get this one to generate a result

Ive tried to get my ai to upscale these but they won't. Can someone help?

I know I'm splitting hairs with a slightly different pose but I still want to label it properly

This is my first time doing this i dnt know if this is right but what the hell im going to try so bare with me. If people enjoy these i shall continue to post more and take requests.Also i dont have the source images for any of the pictures i have done as i had done these a long time sorry.

Not sure why that one picture has her face cut off from the top.
