In My Head: Smirky Smirk

I was listening to "Requiem for a dream" and "Nox Arcana". It really drilled into my head and here's the effect. I thought I would make a quick sketch, I just wanted to do the face, but it turned out into a more...complicated thing. The background took me a while but damn, it was fun as hell

Your task is to find all the hidden words! Good luck and Have fun
