Mapping Corcelle

This drawing maps lark, made to look so effortless by the likes of Dyson, Matt Jackson and Michael Wenham, turns out to be both tricky and time consuming! Who'd have thought?

Anyway, here's my progress on mapping Corcelle so far, heavily influenced by the styles of the three gentlemen listed above. Town walls, the main temple, guild houses, fountains, a wizarding college, marketplaces, river chains and a pair of bridges so far...

No corrections made yet, and I need to find a more satisfactory way of getting the scanned image into a pure black and white, line-art style.

Comments, criticisms and advice very gratefully received.
