Looking good
, just some suggestions:
The maps seem quite empty, maybe just add some dense woodland/villages/farmland.
In the areas where you have something eg. the small town, try and make it seem more alive rather than just placing the buildings. Add some tables, shrubbery and generally make it seem like a town rather than a collection of buildings.
Where you have placed buildings, props etc... texture the ground too make it look like something has happened there.
Good luck, keep working on it and you'll get better!
