Really like them. As for the over highlighting, I guess it depends on what you desire. I think over-highlighting comes out better on photographs, but I am not a fan of it either. But the rest of the troop look as brilliant as your first guy.
Talking of static grass, consider some bushes by Noch or Mininatura. They are a piece of cake to handle and always look good. I mess up my static grass quite often.
