I've always desired to use the Oil Bristle brushes of Photoshop but its high computational load for my graphics card and my CPU made it impossible to do it.
I don't know how but ArtRage can manage these effects without not much effort.
This landscape is based on the Fuerteciudad zone here in Spain, near Sherry Port, in the province of Cádiz, Spain.
I recommend you to visit this province at the south of Spain.
