I'm very pleased with the dramatic results and it was REALLY fun to do. You have to work fairly quickly, while the paper is wet, so it sort of forces boldness and abandon.
I'm not sure how close to done this is. I could
- deepen the values in the sky to make it more dramatic, which might be a good balance with the water at the bottom;
- darken the ochre triangle shape in the upper right hand bit of land;
- tone down the phtalo in the valley at upper center;
- add some white strokes to the water; OR
- call it finished...
