My opinion is much, much different then yours….
In looking at this bitch, she will be 2 in December, so what you see is mostly what you get. I disagree with your comment about lay back of shoulder, I think she is very straight, she is long in the back (compared to what the standard says, square) tail set is pretty good, but she is light in body structure all over. She does have nice feet, however she is what I would call chicken chested and she is pigeon toed (toes point towards each other).. and IMO that will not change. I think her neck is a bit short and I don't like the way it joins into the shoulders. I agree with Andrea about the light eyes. And I think that your Jazz's rear is pretty much the same as this bitch with the exception that IMO, Jazz's tail set is too low, this bitch is a bit better.
As it has already been said, there is no perfect dog... that is why we breed and why we have "chocolate and vanilla"... there are different things that some like or do not like. I have a thing for heads... and can't stand long ears... even the standard says small, erect, hooded ears and they are supposed to be set high on the head, not lopped off to the side... Here IMO is one of the nicest examples of head type for a bitch... and yes, she is mine.
Picture was taken at about 1yr old so she had not developed any cushion on the cheek/jaws yet.

One other thing, there is no such thing with Fanconi as Clear by parents, since this is a linkage test. I would still if you are considering this bitch make sure she is tested first.
