The very first doodle I ever did of what turned into my scifi universe

This was drawn on a post-it note while enduring cubicle life, so excuse some of the blurriness.

My main character is a woman adventurer. She is a veterna of the Shutdown War, where she was a pilot in the militia of an independent human colony that was caught in the middle between both sides of the war. Late in the war, her ship was shot down, leading to a loss of her right leg and arm. Like many veteran humans, her colony was destroyed and she ended up jobless, and inside of a corporate controlled zone. She couldn't fly ships without high end prosthetics, and she couldn't afford prosthetics. Stuck in a low paying assembly job at a ship part's subcontractor, she eventually was approached by another character who provided prosthetics in return for piloting services. There's more to that, but the TLDR is that she ended up with her own ship, along with two crewmates doing independent jobs.

The robot pictured is one of her crewmates. He was another human who served in an independent colony militia as a ground level soldier. Where he was sent had an atmosphere that had biological elements harmful to humans. The soldiers were given 'Big Reds', which were essentially cigarettes containing chemicals to counter-act the harmful elements in the air. The Big Reds were useful short term, but in the long term caused irreparable damage to the human body. Riddled with fatal illness, this character agreed to have his brain transplanted into a robot shell by a scientist needing test subjects for his radical techniques. The scientist ended up on the wrong side of the law for not paying his taxes properly, and ended up gunned down by corporate tax resolution specialists, leaving the soldier in his new robot body on his own.

In the picture the two characters are in a side adventure, being chased by a minor alien species, and in a standard amount of peril.

As you may have noticed, no names were used. This is because while this world has become extremely detailed in my mind, I am terrible at finding and sticking with names I really like.
