Her topline does look off in all of those pictures- try and "clean it up" the next time you take photos of her so we can get a good look at her. She's cute as all get out- but the scruffy look (however adorable), makes it very difficult to evaluate her.
You'll do her a greater service as well, if you set her feet square. In nearly all the photos her feet are going every which way. Understandable, as she's just learning, but really work on that. Try setting her up in front of a mirror so you can see what kind of a "picture" you're making.
You'll need to get a grooming table ASAP if you don't have one as well. Teach her to stack on that. A lot of dogs that stack perfectly on the ground get nervous on a table, and it pays to teach them BEFORE you get into the ring.
Also, as far as the *way* you are presenting her- I don't know how to explain this perfectly, but present her more delicately. What you are trying to do is showcase your dog- display her most elegant features. She's a little thing and should be presented like a piece of artwork. (Go watch some handlers at a show- you'll grasp what I'm talking about immediately). The way you're holding her now, you've got your hands blocking the "picture," and it is distracting.
I think George Alston has a book called "The Winning Edge" for owner handlers, and he does a GREAT job explaining this. Well worth looking into.
Her coat's got a ways to go in terms of growth as well- and you'll have to be very careful of breakage when it gets longer. Many people wrap and oil the coats- changing wraps daily, in order to keep the coat supple and clean. This is the kind of stuff you'd need a good mentor to teach you how to do, so I highly advise you find one. A great mentor is absolutely PRICELESS in terms of experience.
Finally- get some judges to look at her. It's well worth it to find out BEFORE you start paying entry fees, whether or not she's got a shot at all. If you find out she doesn't, you'll also be able to pick their brains about where you could look for your next show prospect.
