@Supremewarrior: That's a big improvement! I know we've been going after you here, but I agree about the colour of the floor. It's really not a big deal, but it'd probably be worth recolouring a little bit (with a little bit of yellow, rather than green, I'd suggest). It's nothing too important, though, I'd be happy walking around in there. Play around a bit with the colours on the floor if you've got a moment, it's good practice for your eyes (colour-selection wise). The back wall is still a bit barren, but that's more a result of perspective than emptiness. One thing I might add is one of those bubble-mirrors they have in convenience stores to the top-left corner. Might be a hard tile to find, though. Don't think Christo's the only one who's noticed you actually care about feedback, either.
@Cray: I think if you added a little bit of shading (nothing too much, the usual three-colour "dark-medium-light" should do the trick) to the chars they'd fit in absolutely everywhere. The discerning eye will catch the subtle palette changes (make them very subtle!) and they won't seem clashing with the earlier SoM-inspired stuff.
