She's very pretty, but I don't see pastel pied or pumpkin pied there. Pastel pieds have a golden yellow color to them. I've never seen a pumpkin pied in person, but they are supposed to be more orange in color.
Breeding is the only way to tell for sure, but my opinion from looking at your pictures is you have a nice pied.
Edit: An interesting difference I've just noticed, is that pastel pieds tend to have a light color surronding their color bloches where as the normal pieds seem to have a darker outline.
My pastel pied for comparison (it's not a good photo and doesn't show his color very well):
