Use a knife and a two sided Japanese saw for cut out the stone foundation
It's beginning to look like the original design drawing.
The cardboard subroofs are marked, first with a 7mm line lowest, then with the shingle reveal distance. Use 3 or 4 mm.
For tiny wind wavelets smear a super thin layer on the surface, then either lifting the surface into tops with the suction under the palette knife blade or a finger tip creates tiny wavelet tops. When dry they glitter ever so nicely like the real stuff
The shingles look a bit too contrasty now, but when blended together by lightly drybrushing with a darkish brown-grey, then highlighted with warm white on the edges, they will look fine.
Use a big bristle brush and dip in the main color plus several other earth colors at the same time, then smear, stipple, feather and generally make a mess. Then clean up with a small brush and add small details and drybrush afterwards. Gentle heating with a heat gun on low setting will open up knife trails and exaggerate all unevenness, plus will round the edges naturally.
Paint with acrylic paint, no washes or powders. Paint with dirty brushes dipped in several colors at the same time to get color and weathering together. Put together walls from Evergreen styrene clapboard (nailholed with a ponce wheel), two Grandt Line windows and a door, plus the storm shutters.
