Thanks for the comments. The plan is to add the name of a town/city to the sign - given the snow, I have thought about Stalingrad with the inference that the soldier is on the long trek back to Germany.
As for it being plain, I do know what you mean albeit this was quite deliberate as I wanted something quick and simple - I could say that there is loads of detail but it's hidden by the snow

The fence and the sign have been kept a little lower in height that they should be to try and give the impression that the snow is quite deep.
I do have another, similar figure but on skis so I'm going to do something a little more complex with him.
