try mixing your ground work material with a little white glue, add some brown paint to the glue and a little static grass until you have a semi thick consistency and then use knife blade to apply it to your bases, it is fast and effective, when dry you can ad some gloss varnish to spots to make it look extra wet, make sure you put a little on the lower legs and hems of robes, but do it sparingly because it is very easy to overdo it. I hope this helps. steveb
