Your name is John White, an scientist who escaped from black mesa in a car. After 1 week of driving, you find yourself with almost no fuel, you enter in a warehouse but you doesn't find anything useful. In total desperation you use a crowbar to break a vent, only to find the beginning of your journey...
weird place for a vending machine...
you never know when you'll need a juice...
Great work, here! My only criticism would be that the vending machine looks way too thin. I imagine it's supposed to be built into the wall, so it might look a bit better if you made a deep inset in the wall just inch or two wider than the edges of the vending machine to convey that better. Other than that, as I said, this looks great.
