Remember that with the mapping options that come with the engine, the ability to express one's ideas may have some limitations. Have you ever thought about making custom maps? In artistic skills, it requires cut and pasting. In mathematical skills, with MV, it requires knowing how to multiply/divide by 48.
If the map does not feel right, keep making more and more smaller ones, for practice. I have seen 2D games on Steam that have had not-so-good mapping, but had also had awesome stories and experiences.
In the next section of maps, I can envision the first one, heavily forested, having all kind of exciting things in the trickier outreaches to the east. The second, I can look at and see a once popular path that is slowly being overcome by nature. With the wide area void of trees, I am curious if a long time ago, this may have been a settlement. I love towns represented by the third map. One way in, and one way out, not confined by one terrain. Well there are actually confined by trees, but the water to the north and northeast gives the feeling of a different terrain.
Post some of your maps to RPG Maker MV Forums. People will critique and give advice.
