AN 'EMPIRE' AT 40: MARCH OF THE WALKERS!

Unused storyboard angle of the Walkers. A visual idea similar to this would appear during the Battle of Scarif, in Rogue One: A Star Wars Story.

The force of approaching Walkers continues on against the Rebels in a wide spread attack formation, in these intriguing storyboards from Joe Johnston for the Battle of Hoth. 

Another Johnston storyboard featuring an angle of ultimately unseen Walker movement.
