It felt satisfying seeing the full scene after opening the preview, great way to play into feverish little expectations of the brain. The mottled blues and greens from the desaturated color wash really make the stark lighting give an inhuman edge to the characters. It seems both are the same individual, with one side oppressing the other. Quite a fun concept. Primary critique would be that the glasses would cast a different shadow, possibly with a red tint, that doesn't appear present - this stands out considering you have defined very intense shadows elsewhere. It does not detract from the overall visual though, so still a fine drawing!
