Ok, some quick thoughts. Form should follow function. Keep that in mind when thinking about what makes something Cyberpunk. My advice is to get your ideas down on paper, it's way faster than modelling. Stop using the mirror feature so much, asymmetry is where it's at.
The door, I think it's off to a good start, but again, I feel it could use some more edginess. Take the panel off the left side, and put one higher up with a light or something in it. I am not a huge fan of the door itself sliding down. The logistics of this are a lot more difficult than a sideways sliding door.
The apartment. I would not use the mirror for this. Think less about the floor plan, and more about where it is, what kind of building is it in? What kinds of facilities would have to be implemented for things to work here. Vents, ducting, lights, gears or pistons... Design the feel, the place, before worrying about modelling.
The bar. This is a decent start on a fairly basic bar. Slapping a tube on the bar doesn't make it Cyberpunk. I would think more about the components of the bar, is it rounded chrome, in some fancy corp building, is it a bar from the mix, made up of rusted metal sheets riveted together? Maybe the stools are made from car tires, or random metal they could scrap together.
Overall I would say, push your angles, and think about what kinds of mechanics and what not might be here. I threw in a little thumbnail of a hallway, just to illustrate how you can use odd angles to add more atmosphere.
