Quick update...
Since those screenshots were taken we've worked on and improved the following..
Curbs - look much more realistic now, very pretty
Tarmac - closed the difference in colour of old and new tarmac
added more detail including wear and tear - but not too much
Grass - Stopped the 'tiling effect' so it doesnt look like its been used over and over
DECREASED saturation but brightened it slightly, looks great

Screenshots coming later tonight
