Thanks guys. I just had a few hours to finish these, and had to resort to some quick pops. The whites are cow parsley, but only one pop of bad manufacture
Same as the lily pads. That will be improved!
The terrain is based on a blue-red heightmap from AHN (unfortunately they have a flexible system, where the reds change when you change the close up area, so it's hard to stich a high res map from several views), and I added some 4000x3000px greyscale maps for the 'new' ditch versions (softer edges), raised dike, and the heathland terrain.
So no river setup, Doug.
For the people living there this is indeed a nice terrain to stroll through, as it's a few hectares surrounded by masses of industry and glasshouse cultivation! See this (bad mapping too, still).
