The most obvious problem is the composition, or framing.
It feels like you should have put the camera a few decimeters to the left. Theres soo much negative space on the right.
It's too blurry, even for portraing a motion.
The camera isnt focused properly, it should be perfectly focused on the soldier in the forground.
The posing is decent, but the soldier in gray is kind of akward, because hes neither walking or staying.
The lighting is great.

If the camera was a little to the left and the blur was a depth of field effect. The lighting is good and it's got potential, keep up the good work ;).
