I'm seeing coincident surfaces in the window, and doorway too, I believe.
Better scale those cutout boxes slightly upward in the facing direction,
translate slightly too if a side is on a zero plane.

Sandstone could be done by using a very small scale granite normal but it
wouldn't show up on a unlit side.  So a texture layer of granite pigment and
normal both over the one you have now would be better.  Just use a small enough
scale.
There's probably a sandstone in the stones.inc file already but not everything
is labeled enough I think.

I added a sandstone into that file (just looked) but since I changed much of
the naming scheme I'll just put a stand-alone one here for an example:

sphere {0,3
texture {pigment {rgb <1.2,.9,.4>}
 finish {diffuse .9 specular .1 roughness .1}
 }
texture {
pigment
 {granite
  turbulence 0.4
  color_map
   {[0.0, 0.1   color rgbf <0.8, 0.5, 0.4, 0.0>
                color rgbf <0.8, 0.6, 0.5, 0.6>]
    [0.1, 0.3   color rgbf <0.8, 0.6, 0.5, 0.5>
                color rgbf <0.9, 0.5, 0.35, 0.3>]
    [0.3, 0.5   color rgbf <0.9, 0.5, 0.35, 0.1>
                color rgbf <0.85, 0.7, 0.4, 0.0>]
    [0.5, 0.7   color rgbf <0.85, 0.7, 0.4, 0.0>
                color rgbf <0.8, 0.75, 0.5, 0.2>]
    [0.7, 1.0   color rgbf <0.8, 0.75, 0.5, 0.3>
                color rgbf <0.8, 0.5, 0.4, 0.0>]
   }
 }
 normal {granite .5 turbulence 0.4}
 finish {diffuse .7 specular .1 roughness .1 crand 0.1} // use zero if
animating
  scale .8
 }
}

In addition to what Bob suggested i would also add a brick normal to
emphasize the structure of the walls.  You could also build the walls from
single stones, but it would be slower and more difficult.

I wonder about the green lines at the top of the walls.  They seem to be
slightly sloped but i can't imagine why.

	Sandstone comes in many types. Be certain to have a picture of the kind
you want while working.

It all looks very sharp and angular, you really need some soft edges in
there or even area lights to soften it up a bit.

The green lines are part of a sloped roof (the buillding is moddeled on a real
building which is used as a church)

It already has 2 (2x2 arrays)

But then something went wrong with the left part.

It's something that is causing problems in trying to get the rotation exactly right
btw sorry about the spelling mistake in my previous post.
