That change to a closer, better seen Sandcrawler element is one of my favourite changes.
Sure, it wasn't a biggie in the scheme of things, but I reckon it looks far, far better than the previous 'dot' in the distance with the dreadful 'reflection' flash. And the whole new shot (and excellent skies) seen shortly after, is a HUGE improvement to the original version - http://picasaweb.google.com/doubleofive/ANHRVisualComparisonPart1#5184276470873014866
