Defining the darkest of my darks

Next step was to define the deepest and darkest areas of the paintings..those are mainly shadows within shadows.I also laid down the background for the tree pn the left,bushes at the foot of the kasbah and the trees and bushes on the right bottom.
It is,I believe,wrongfully assumed that the foreground in a landscape painting is the most important part,where action takes place,and where details are carried out in the finest of details...well,while the foreground is visually the closest part to the viewer,it doesn't have to be the most important in the sense that everything that happenes in the painting should be jammed therein.
In this painting in progress,the focal point isn't in the foreground,so I'm keeping it shadowy and dark to reduce it's visual impact on the viewer and therefore reinforce my sun-bathed focal point,and create more depth,and above all,bring more drama into the painting through this play of light and dark.
