I am now creating a camber in all the roads to create a more realistic feel - making a gentle curve from curb to the crown of the road.
Work in progress screen shot showing how this looks.
I have also made a render of the service alley. This is the first render that I actually feel I'm getting close to with creating the kind
of realism I imagined originally.
I have the image below as wallpaper set at 1920x1080, which looks kinda cool on the desktop. I want to add a delivery truck to the alley eventually. All the vehicles are courtesy of dmi-3d.net.
