Full Moon Over Cuckmere Haven - stage 1

I am returning to a favourite landscape as possibly the last in this series as I try and consolidate what I've learned (if I have the time I might do a post about the whole series and what I've learned from them). The location is the iconic Cuckmere Haven on the South Coast of the UK about three quarters of an hour away from where I live. There will be a single light on at The Coastguard's Cottage and everything else will be moonlit sky and landscape, the moon unseen just out the top of the picture although you do see it reflected in the nearest curve of the river. With a bit of luck I hope to have the whole thing painted in one day, tomorrow.
This stage was "drawn" up first with a small bristle brush using a mix of Burnt Sienna and Manganese Violet thinned with Liquin which I allowed to semi-dry over a few hours and then later this afternoon I finished off the sky and the rest of the tonal underpainting with a rag using the same paint mix.
