I drummed up the courage to tweak this after helpful comments here and on Wet Canvas. What I did was to work on the foreground land first of all. I added rough strokes of Naples Yellow, Burnt Sienna and Raw Umber and then blended them in with a rag to soften most of the edges. I then turned my attention to the water. Here I used mixes of Indanthrone Blue, a touch of Alizarin Crimson, touch of Raw Umber and Titanium White to produce a variety of tones that would give a better range of contrast as well as get rid of the highlight up the left bank. Having just finished painting I'm not sure whether it's done but my first thought is that it's about finished. Any comments?
