I began building up detail and refining areas. Here are some close ups as well as the final result of my day’s work.
Lots of color in the base for the sky.
The blue from the sea is bleeding into foreground.
In painting the tree there are several approaches, paint the the shape of the branches or focus on the sea between the branches. Do both.
The painting ir roughed out pretty well now, recognizably land, sea and sky. From here on the work will be subtle fine-tuning.
