On a strictly perspective aspect I think this is perfect. You got that triange and the rule of threes. The cute head and the two paws. What really sticks out to me after those eyes, is the fact that you got down to her level. To me it actually give's the whole thing a 3D effect, especially with her left paw extended a little more forward than the right paw.
And I just plain love black and white pic's.
If I could change one thing, I think that I would have given it a wee bit of a darker background. She would have stood out a little better. All in all a definite fav in my books.
BTW what does she got.
