Tower Of Babel - stage 1

I changed my mind about doing another night painting as I wanted to do something that expressed the space of the landscape in Utah, this is called the Tower Of Babel and is located in the Arches National Park. I fancy painting something looking towards the sun for a change (I used to paint most pictures up to a few years ago in contre jour light) and have an idea for how I want it to go but I have another idea as to how I can light it so I will decide tomorrow morning over my breakfast coffee when most creative decisions are made!
This stage was "drawn" up with a small bristle brush using my usual mix of Burnt Sienna and Winsor Violet thinned with Liquin.
