Glad you like it Alexander !
The figure is actually supposed to be a GI. It's from a Milicast set, and up close it looks like an American soldier with an overcoat and a general purpose cap. I admit that he might be a bit browner, but that's part my own fault and part the lighting. So the setting is just an sWS captured by the Americans.
The program is Photoscape and I simply used one of the built in features, which doesn't take more than 5 minutes.
HTH
