Here's an early design idea for my lead character, Nathan or 'Nate' (not sure about the name yet).
Even though I'm wanting to bring science fiction ideas into this project, I'm wanting everything to remain 'grounded' and believable. So fashion and clothing, for example, wouldn't be massively different to what you may see today. The sci-fi elements would also be part of everyday life to these characters.
I also threw in a 'heist' design variant too to see what I could come up with.
