Doesn't look like a Pastel, but it does look like a really light normal. It could be another morph, but most likely it is a very light normal, very beautiful too.
And holy crap, that is a huge scar in its back.
EDIT: It kind of looks like a Fire to me, but I could be wrong LOL..
You don't normally find BP morphs slithering around the outdoors. Especially in the United States LOL.
