So to answer your question... I checked out the work of a kind person who commented under my piece, and it turned out that I have already seen it yesterday, lazily reading half way through the description and I felt guilty ;) Jokes aside, it turned out for good because now I noticed the hand knocking the door and it all made more sense. Oh and I listened to the song.
...and if you say you like some unsolicited critique, I'll do my best :D
I think that the first thing that stands out is the bird-eye perspective, which adds to the feeling of isolation/solitude. The concept of warm vs. cold light resonates with me, but in my personal opinion the difference might have been a little more pronounced? The patches of light on the wall are quite faint, and the glow on boy's face rather tiny when seen in this size on an image. Maybe if you would sacrifice some subtelty the concept would be more readily-readable (I cannot guarantee this word exists, though)?
Anyways, I liked it and good luck :)
