This ended up coming from a random idea that popped into my head while I was listening to the song 'Storm' by Lifehouse. I'd watched the end of Kuroshitsuji II earlier and the lyrics just made me think of Alois. These were the particular lyrics that inspired this wallpaper:
Barely surviving has become my purpose
'Cause I'm so used to living underneath the surface
If I could just see you everything would be all right
If I'd see you, this darkness would turn to light
I'll admit now that it was a real challenge to get the water and bokeh effects right, and I'm still not completely pleased with it, but I feel like it did turn out close to what I wanted, so I decided to go ahead and share it.
