When I imagine a sustainable future I don't picture massive maga cities but small communities working collaboratively. 
For me sustainability incorporates a harmony with nature. I was inspired by the copious lavendar plants dotting the landscape surrounding my home, populated by bees in a living ecosystem. 
From this reference, my agents of change are working together to both care for the local environement and setup new communication technology that keeps us all connected.

In my initial sketch I've incorporated the lavender and bee hives atop a natural high point. The new antenna being setup is supposed to be more visually appealing opposed to the towering masts of today.
For the surrounding landscape I want to showcase the small towns and villages nestled into the valley. Hopefully I can make it look cosy in the final painting!
I'm trying to avoid a standard daytime lighting setup, though I will need to make sure that the piece doesn't feel too dark or uninviting. 

Enjoying the process, looking forward to colour next!
