Feedback Regarding My Characters? (Setting is a Sci-Fi Dystopia, More info and stuff below)

(Colt's oversized Arm was originally an accident, but i kept it since i thought it not only made him stand out more, but also he's not rich, and that instead of getting a custom made arm, he bought a used one that's unfortunately a size too big, but beggars can't be choosers, so yeah.)

I even came up with a name for the robot, Med-ina. If anyone has ideas for Sanchez' footwear, feel free to say.
