Refining the mountains, rocks and trees
I realized when I had finished the previous step, that the top lines of the mountains on the right were parallel, which I needed to correct.
I added a rocky shore line on the close right mountain and defined the rocks, particulary those in the foreground, where I was putting the rocky overlook. I didn't think the sun was shining on the trees, so I highlighted the sunny side a bit more. It was a semi-cloudy day when I did the plein air sketch, and so I am having to fabricate the sun on the trees.
