Portraits on the run

This weekend, I tried to capture a portrait of Natalie. Natalie doesn't stand still for very long, so it was a bit of a challenge. Most of the pictures turned out like this one:
Then, there was this one where she is actually saying "Cheese" - or maybe she's practicing for Halloween...

But finally, with a little cropping, I got this one. It may be a little grainy, and I'm sure the lighting isn't quite the way it should be, but there is something about this picture that is just right.

This is Natalie.
