there's a lot of rivers, i don't know the geography of netherlands but i'd make sure the main rivers are in the map, and the less known could be there for gameplay while others you can ommit and replace with a territory line instead. you really should have all territories of the same region at least touching/connecting to at least one other of the same region for intuitive sake. therefore, i'd replace those rivers with territory lines. (if it makes sense geographically) or just keep the bridges there.
for gameplay demonstration, i have just stuck a whole bunch of bridges so that there is more manueverability around the map. we don't want this many bridges. this is where i would look to see if a river needs to be there?
the bonuses have changed according to the bonus calculator.
edit. i'd probably make sure these rivers are definitely there, and look at where you don't need others..like the ones that are running through the same region...and keep the ones that are separating regions for region defensibility
edit. i would looked to see if these rivers need to be on the map.
