Water Wars

I'm doing a themed exploration: the theme is a rather dystopic near future, where climate change has brought on drought. I know it's not very original, but it's where my mind wanders.. I first wanted to do some cool Mad Max-type stuff, but as I was working on it, I realised I wanted to give it a little more of a realistic feel.
I'm also using this to get to grips with the Redshift renderer and a more 3D-based workflow in order to get compositions quickly, and to be able to generate more than just one image around the theme/concept.
I'll try to do some more and post process pics.
