Now, let’s do a little more work to the base of the mountains and the trees. There will be a thin section of trees at this area around the base. Let’s put some shading here under where we shaded earlier. All of this shoreline area should be in the shadow of the tall mountain peaks of the left.

Begin sketching some very simple representations of the tops of the evergreen trees under the right peaks. It would be helpful to erase the top guideline from earlier first. Then begin sketching the sides of the trees in front, as well as the tops of some of the front trees that are shorter than the ones in back.

Just a little more shadow areas are needed near the base, and I think that’ll do it for now.
