Novice - Free walk on a long rein across the diagonal

There are different lines for FW on a long rein in the Novice tests.  

This video shows a long and short diagonal. You need an energetic walk where the horse over tracks well, stretches down and takes the contact forward.

The rider should look to where they are going, keep their shoulders up and slowly release the rein as the horse drawers it forward.

When returning to medium walk progressively take the reins up making sure you keep the contact.  

In this video the horse has good walk steps but needs to take the contact forward and down more which would then give him an even bigger overtrack.
