The one & only window at the Four Mile hut, surrounded by all sorts of rusted pieces of tin, with most being from old tin drums/cans, that formed the walls of this amazing little hut (my fav of the many huts that we walked to). You can see a shot of the hut here - http://365project.org/leggzy/365/2016-12-28 (the window is on the opposite side from where my shot was taken)
It would be very dark in the hut with just the one window. It certainly is an amazing looking hut. Great shot of that one window with your reflection in it.
Including your reflection was the right idea - the reflection becomes the main subject and the textures of the surrounding hut become secondary, which I think makes them more interesting.
