Nice chapter. I personally would prefer some more descriptions of the environment, the people and the progress of time, so I could sink more into the story, but on the other hand, it is easy to read the story in the evening even when you've not got that much time.
There is definitely some tension, but as the chapters are always very short I couldn't connect to the characters on an emotional level yet. I don't know if that's intended or not, though.
However, you keep going and improving, I keep reading!
