This illustration is based on he first page of the french graphic novel Carbone & Silicum wrote and drawn Mathieu Bablet and published by Label 619 (http://www.label619.com/fr/albums/carbone-silicium). It’s a cyber punk master piece that you should read if you like this genre. For me it’s as important as Blade Runner Akira, Matrix, and Ghost in The shell
Evey piece is modelled in Blender, mainly hardsurface and modular, and render with Eevee Engine, with a few post prod, also done in Blender.
