This image in no way suggests 'distance' to me. It would work for a 'movement' challenge, or 'blur', but not distance.
In addition the vehicles behind are a distraction and in no way enhance the image.
My suggestion would be to crop the bottom third horizontally, then work with Constrast or Selective Colours, to bring out some depth and then maybe add a slight black frame.
This shot isn't very sharp, and what I am looking at, the trees, or all that stuff I can't really make out in the background? This is a confusing shot.
