advertisement for Hitachi? the rotation is wrong. if you have taken the photo horizontally perfect, this shot could have been Hitachi's poster to promote their crane product! nice. a 9 for you. a 10 if the rotation was better.
Artisticlly, the diagonal of the construction equipment is so strong it is actiing like a wall to stop the view of the background. Area in forground is a bit dark.(shadow area on the ground has no detail) better exposure in the camera may help but you may have eliminated this problem in processing.
