Composition: Not bad, but it is a little bit cramped. I feel. Too much foreground.
Pose: Ah - that's what it is. It's the little bag. When I was a kid, those tiny plastic German soldiers had bags like that. For the nostalgia.
My brother used to be the Germans. They had machine guns. I had the British...they all seemed to have their bayonet equipped rifles pointing up in the air, and hats with foliage on them. The game was that you could shoot whatever your gun was aimed at. My troops didn't stand a chance.
