I need you to take a look at the catchlights in her photos. See how they're smaller, brighter and higher than yours? She has specifically shot for this style. Whereas you have taken a lovely but "regular" photo.
My understanding is that eyes are usually enlarged slightly during this kind of editing; so I hope you don't mind that I did that, and a little bit of facial sculpting.
What do you think of this?
I hope I don't offend anyone by saying this, but I think race is important here. Can you choose a sample photo of somebody with a similar complexion to your subject?
