It looks fairly decent!

some crits that I can suggest either this or the next map:

1) the black stroke around the trees and the buildings seem too bold, though there may not be too much you can do about that if it is scanned in.

and

2) the various tones of greens and grays/blacks seem bland with no contrasting colours. I would focus on making your towns and buildings stand out colour wise (maybe a roman theme with white walls and red roofs, or just some brighter/saturated browns.). Maybe take a look at some architecture of buildings from the setting you are looking for, and identify predominant colours, if you feel so compelled.

Also, I think it would look better if your castles dropped the brick texture altogether.

I do like the hand drawn style though; it could use some refinement though
