Now finished:
(Note the very last picture isn't completely done, hence the clearly visible flat background.)
As always, i love opinions.
(Also, once the map is realised i advice to NOT drive on it with articulated busses. (and on line 620, not with anything larger then a midibus), due to small busstops, but also that some of the curves aren't designed to work well/are even possible with an articulated bus. This map is made to be pretty challanging on it's own for the bus sizes it's made for.)
