Woah! Now I can't keep up with the ideas brought up in your comments. Thank you for them all!
In general I must say there won't be many more updates for this particular background. I'm rather happy about it now, but more importantly me, Baron and Thomas need to quickly finish the new content that will go into the final version of the game. Sorry.
@ALPHATT Thanks. I was definitely no friends of perspective while making this background. And I liked having some elements of the background feel rushed.
@Kaio A stronger more defined left edge of the bar might be a good idea. The door is like it is, because I tried to make it extra ugly. It's a metal door with a pink paint-over and a lot of dirt on it, there are scratches in the paint and in some areas "the pink" has given away completely. The door had even a picture of a duckie at one point, but I felt it was too distracting.

The white spots are to make the walls seem chopped and the whole background look rougher.
@InCreator That area was actually meant to look like a bathtub full of smoke!

I'm unable to explain why though. And, no, it wasn't meant to be some awful fart joke.
@RyanTimothy @markbilly My response depends on what version of the game you played. If you played the version released for the MAGS deadline, then I must admit I messed up a bit in this specific matter. The idea was for the player to overhear bits of a disturbing dialog when wandering around the bar and feel compelled to search for the voices source. In the initial release I screwed up with defining the voice hearing areas - the hero could easily avoid walking onto those areas entirely. For the player who proves to be insensitive to those subtler suggestions, there's additional pointer. After getting his drink Jack overhears something very specific and asks "WHERE DID THAT COME FROM?". I find these to be sufficient enough hints.
