N scale layout "Hills have Castles"

Hills Have Castles !

 There is  a view of the left hill . I made a base for the castel  and then fit tested it many times . After that , I was bale to  start building the road with blue foam chips.

 I then  used the faller putty to cover all the area . When dried (it has a curing time of  10-15 minutes)  I was able to spray the  first color layer.

 Another view  a little more far.

A more overall view ! The 1/33 of the layout is trully colorful  and the rest is .. grayscale...  .
I  , here ,  have no clue  what to build in the front left corner  and on the  far right corner. Maybe  two farmhouses  could be nice .
