City of the Sky People - stages 1 & 2

Stage 1

As mentioned in my previous post I intended to paint a more naturalistic sky and landscape but with much more of a Fantasy content so I came up with this: an imaginary city set in a cold and desolate landscape against a big sky, this time painted in more cold, naturalistic colours.
The river meanders are influenced by Cuckmere Haven, an iconic landscape half an hour away from where I live in East Sussex UK. I think I'm channeling a battleship's conning tower for the city!
The first stage was "drawn" up with a small bristle brush using a mix of Burnt Sienna and Winsor Violet thinned with Liquin, Lukas Number 5 medium and turpentine. The Lukas Medium was used to speed the drying time so that the morning session for stage 1 was dry enough for the application of a tonal underpainting in the afternoon. This used the same paint mix but with more turpentine so that it could be applied with a rag.
