I think it emphasises your creativity when playing with space. Perhaps it's my background in art and interest in interior design talking, but I enjoyed your use of negative space. It really emphasised the central theme of loneliness.
With simple language and masterful structure, you've managed to cleverly convey a lot of emotion in a clean manner. This is a good testament to how immense detail does not necessarily equate to immense emotion.
I don't typically like unconventional poetry due to a lack of substance, but this is really really good. I'm very impressed by how you managed to convey so much so simply.
