Craters and Shell Holes

In an upcoming WW2 game, there is an area that is cratered from shelling - so, I grabbed a package of Games Workshop Moonscape to represent the shell holes. I painted up one "as is" and I think it is passable. Certainly a ton easier than constructing my own from scratch! I am thinking that I'll modify the next one a little, adding lose dirt and some stones. We'll see how that looks, then I'll do the rest of the package.

What do you think about these as shell holes?
