I went back over the 3 stands that I was unhappy with and improved them. I am happy with them now. The bases were too white. I wanted to break them up with mud, grass and earth more. Here's what I did:
I ended up going back over some snow sections with my regular ground mixture, making it dark again. While the ground mix as still wet, I sprinkled some 6 mm static grass onto it. Brush this upward using a soft brush if you have too. You wan this grass sticking straight up.
Once that dried, I drybrushed the grass a dark brown.
I went back in with the snow paste in and around the grass and while that was wet, I sprinkled some WS Soft Flake Snow on top of it.
Where there were low depressions in the ground, I put a few drops of WS Realistic Water and let it settle. Then a very light mist of Soft Flake Snow on the Realistic Water
So, here are the finished snow bases. Comments?
