Yes exactly, its very nice and stunning what you can do with those. I have actions creating cloudlayers, colerfill and textures. The only wonky thing is that the actions tends to messup when you record the change of layer orders. So always give them specific names.
New Trees for the DeRust Set, they are realy realy tiny, but intended for a more Pattern like effect. I hope they work on the map.
I really like it ! How did you achieve that water ? It sure does look gorgeous !
