Nice little village!

May I suggest some improvements?

Increase the contrast between light and shadow, it would look more like a warm sunny day.
You can set the values in the lightmapper to a warm reddish and yellowish colour for the sun and to a colder bluish color for the shadow.
And increase the contrast of the grass texture.

You seem to use a plain ground without slopes.
If you actually do so, it would be an easy way to 'connect' the walls better with the grass when blending the grass texture with the wall texture at the lower edge in a painting program.

Another hint, although I don't know how successful it would be in its results:
switch off the blur in the lightmapper, and adjust the regions where you need blur in the paint program.
