May I offer a bit of advice as well? I noticed from the first pic that you're trying to balance control between the lead hand and the hand you're using to adjust her legs/feet with. Just for practicing (and can be used in the show ring) try grasping the lead closer to her head/neck, to give you more control there, and that will give you more balance and freedom to make the necessary adjustments on the hind end. Here's an example of when I was practicing with Debo before I showed him...
Notice where my hand is holding his collar? I know it's a rough stack, and he's a bit stretched out, but it was good for me to look at and see what I was doing wrong, so if I can show you in order to help you out, I'm more than happy too.
Here's another shot (sorry for the poor quality) at an actual show, in the line up. Notice where my hand is? The closer to the head you hold on to the lead, the more control you have over the dog.

Hope that helps you out.
