A personal project I've done this year to learn how to produce efficiently an environment, based on concept art.
My goal was to learn how to optimize my workflow to produce the final image fast and not put the effort into the production of each individual 3D asset.
So this image is highly inspired by the matte painting of Jacob Scamell: https://www.artstation.com/artwork/YXYKd

First I wanted to do all the aspects of the final image in 3D, but I choose to finish the foreground in matte painting to respect my deadline.
