I really love this shot... the lighting and shadows were nailed. The scenery is awesome... cloud cover is just right... small village in the valley gives something else to look at apart from just the ranges... crafted looks great and is well lit...
Just one nit-pick which may be entirely personal... I would have positioned the craft slightly lower, nearer to the corner... to give the effect of the GR4 rushing past the viewer in a turn.
Very well composed shot Immelman.
