Pastel is a tricky and subjective trait, especially when you get to albinos. Some just scream but just like there normal counterparts there is degrees. One thing about pastels is they develop color as they age. Again some intense some more suttle.
Here is a pic of a nice pastel albino

Your girl I would say is a lower end pastel. Don't take offense she is gorgeous. I expect she will keep nice color and defined markings compared to almost flat yellow most albinos get.
