I have some remarks on your maps.
- First, we can see aliasing in the top-middle left of the map. It is not very important, but If you are perfectionist, it can be a point to improve. ;-)
- Second, your town. The town is built on the beach close to a river. Darn, if one day there is a storm, all the town may be destroyed (flood and tidal wave). In my opinion, some houses are too close from the river (explanation below).
- Last, there is something strange with your river. Usually, the river is confined in a channel, unfortunately it is not present in your map. Ok I cannot explain very well, but is it possible to surround your river with some yellow texture representing your channel?
