Very nice PS work indeed! Good use of diagonals in the composition, with the slope of the ground and the dark clouds at the top coming down to meet the ground almost. Creates a rule of thirds only in triangles instead of lines, sorta. At any rate, it works!
Nice shot - Like the tones - The pic feels a little off balance though with both main subjects at each end of the frame - I understand that these type of shots are hard to get so well done on the technicals.
