I put out all my colors on my palette, and worked over the underpainting. I like the glow of the sunset and the way the rosy color flows over the entire scene. I used a fairly limited palette of warm colors: lots of cadmium yellow light, cadmium red light, burnt sienna, and cobalt blue. And of course, white.
The major change that I have made is to move the town to the right. You can see in the original photos, that the town is adjacent to the large tree mass on the left. For balance sake, I need to move it so there would be something of interest on the right. As I go along, I will figure out exactly what buildings and houses will be where. I am thinking of just a few houses with a church spire rising above some trees. Perhaps on the mountain I will put some spots of reflected light from a roof or two.
I have also added trees and bushes along the bank, which previously was under the bridge and very austere.
I propped the sketch on an easel for review. After many passes by, I found one area that really jumped out at me. When my eye keeps going to one area, I can figure there's something wrong there. In this case, look carefully at the top sketch. On the left, there is a dark area of water that traps my eye. The shore line above it and the foreground shoreline form basically a mirror image. There is no flow or interest in this area. My eye definitely gets stuck here.
In the bottom sketch I have added some scrubby green bushes which soften the bottom shore line and gracefully leads your eye into the back shore line. Everything else between the two sketches is the same.
