I really like the mood of this piece! It's almost like those cutscenes in old adventure games. I almost expect that after the "day after" text when sceen fades in again, the guy would have a knife in his back and some C.S.I dudes would be investigating the room and then you, as a main investigator would have to start searching evidences etc.
That's why I LOVE this!
There are lots of technical issues if we speak of pixel perfection, like banding etc. but I forgive lots of those, since the old adventure games weren't also too precise about pixelling techniques more than what gets the job done. Maybe that's why your style is so authentical
