The settlements will have different symbols (one hut for thorps, two huts for hamlets, 3 huts for villages), but that should come in a later stage of this map. Cities are few (in this section, only the boat is a city--a port city in this case).
A scale marker and a legend will surely be included. This is just a rough first draft to see how the things will become. I'm not sure about what you could suggest about the colour theme, but I will think about it.
My main concern is: is this detailed section a good reference of the bigger scale section (remember we are talking about 500% zoom here)? Did I place the forests and hills in accordance of what should be expected from a region like that (where plains should be the main terrain)?
The detailed map resulted from some random placements based on what I thought it could belong to the map.
For example, there are 60% chance of plains, 5% chance of ponds/lakes, 5% chance of light forests, 7.5% chance of forested hills and so on. Did my placement by random chance did any good/bad to the map?
