This is Shane Walsh taking aim at a unknown target. I really dislike this figure as it is hard to stand up and has very little articulation. The diorama turned out better than I expected, though. I have started using a small piece of wood dowel(painted black or to match base) and a small strip of a velcro cable tie to hold my figures in place. It works well enough to keep them in place when I open my display case and doesn't look to bad.
