I'm far from an expert, but these are what TOP examples of the Suri local look like.

Look over the pictures in the link. The breeder is VERY reputable and only sells top quality animals.
That said, if you love your girl already and KNOW its a girl for sure. A Suri cross should get plenty large. She may not be a cross either.
I'd get her probed to make sure you didn't get screwed there in case there are questions.
But I like the snake and am very happy for you.
