The first stage begins the process of tweaking colors toward realistic ones. Here's where I am right now:
The lake is coming along -- again, a little drying, then a touch of peach color to reflect the sky.
The beach below us and in the distance has its initial laydown -- needs a little darkening.
The dune in front now has dark and light grass underpainting -- next for them is modeling using light and shadow.
The stand of jack pine and scrub has its dark underpainting -- modeling next.
Areas representing sand are next. Everything will depend on this.
Final touches, way into the future, includes the tiny details -- strokes that become blades of grass, tree trunks, splotches of shadow, skims of highlights.
