the buildings are looking good.
as for Aussie Western inspiration, Wild Boys has just started in the UK on TCM (taking up the time slot left by the end of Hell on Wheels). I know it aired in Australia back in 2011, but i've no idea if its been on in the US. I also remember some kind of serial drama that was on in the 90s/00s. it really didn't interest me at the time as it seemed to be day time tv melodrama, so i never really watched it. Google-fu tells me it was "Snowy River" or some such thing. probably not interesting televisual entertainment, but might prove inspiration for the setting.
