Thanks everyone for the comments. Since those pictures were taken, I have dusted on MMP pigments throughout the rubble and the house and brick wall. I debated with myself on the issue of rubble by the brick wall (Scott is correct, it is made by Kancali, a member here). I myself could not decide if the wall damage was old, non-war related damage or not. As the consensus seems to be rubble by the wall, I shall go back and add it. Also, as for additional rubble in front of the house, as the front of the house is nearly undamaged, I thought most of the rubble would be behind the house and thus off the base.
For the specific questions not related to "dusting" the structures: Harrison, the tall grass is Heki that I purchased from Scenic Express (Savannah, 1574). Francois: there will be 6 figures and a Dragon Panzer IV Late J, check my earlier progress reports for a look at them. Robert: there won't be any snow, this represents the close quarters fighting in the twin villages of Krinkelt-Rocherath very early in the Bulge fighting, before the arrival of the snow. It was very foggy, which enabled GI bazooka teams from the 2nd and 99th Divisions to get in close and knock out many German tanks. This diorama will have 2nd Division GIs. Also, Heki recommends that you first have a layer of static grass down prior to attaching their grass (done in small sections and attached using diluted Elmer's white glue). As for the color of the grass, I live in Houston, so our grass remains somehat green, even in the winters where we have freezes, so I did drybrush the Heki to make it more of a cold damaged look based on my experience, maybe not enough for a truly cold climate?
Again, thanks for the comments, more pictures will follow once I am finished.
