I love this piece, the moon, the girl's expression, the details of the town and the details of the reflections. I have one criticism, and that is that looking out from a lit room at night, you would see the city through the patches of glass that are less well-lit from the interior light. Similarly, the places on the window-glass where the interior light strikes most strongly will obscure the view of the city and reflect back a bright image of the interior. I definitely applaud what you're doing in terms of showing the reflections in the windows, perhaps they would look more realistic if their placing were reversed.
Keep up the beautiful work!
