Sci Fi Vehicle and Environment

Happy to show my latest personal work! This started off as a game-ready asset exercise that eventually morphed into a full environment......Might have got a bit carried away!
//
I'm a big fan of Giorgio Baroni's Vehicle designs, and when I saw his concept of this little cube on wheels, I knew I'd have to take a shot at it one day. The design has a clean, minimal aesthetic which I really vibe with but also has some bold shapes and lines which I love. The sketch also allowed me an opportunity to make a few of my own stylistic choices that I hope do his concept justice.

In terms of the environment I wanted to create a simple scene to help tell a bit of a story as well as create something that complimented Baroni's design. I stumbled across a photo of a tunnel midway through modelling that sparked a bunch of ideas and an opportunity to tell a bit of a story. I love Sci-Fi that's relatively minimal and keeps me asking questions so wanted to keep the scene a bit vague as well. Where was the driver going? Where have they gone? For what reason? Is this even earth?

I really enjoyed adding a bit of life/nature to the scene such as the water, smoke, dust and various other atmospherics. It was a challenge to try and keep it understated and not too distracting. I originally played around with a version that included vegetation, but felt it took away from the harshness of the environment so ended up removing it.

All assets were made by me excluding some Megascans rocks and textures as well as some brush/grunge textures by Jan Wyss.
