The Lost Cathedral - stage 3

I forgot to mention yesterday that there is also a Debussy reference to the title as I had the title of one of his pieces, "The Engulfed Cathedral" in the back of my mind when thinking about this picture.
It was a nice bright day in my studio today so I was able to get in a colour underpainting finished based around a red/orange - blue/green colour complementary. I have kept the values away from being too light as I intend to paint in the snow with opaque mixes on top of middle/dark values.
