The minimal details work so well here. Apart from being aesthetically pleasing, it enhances the mood of intense emotion and pain. It's more about what we can't see than what we can. Thank you for sharing.
I love how you're so inspired by NIN. It's almost impossible not to be though, I found myself too deeply immersed in dreams when I listen them, and as irrelevant as to mention; I'm most likely to have a tragic car accident.
Quite a masterful use of negative space. There's so little to see but, for some reason, I don't have any problem with it. The harsh, but scarce, light and the stark contrast pair nicely with the deliberate gaunt, sunken eyes and reinforced distress of the mouth. It's THE expression for a piece like this.
