Hi it looks like you are in SE Asia? near the coast? if so I wouldn't do stones above 1 meter or so because of earthquakes and because of the general poor quality of the sand used in concreat there. large stones around the house angleing in as they get higher (aztec pyramid style) 1 meter high with a ledge of 10 cm or so at the top. Wire reinforced fresh stucko painted a lighter complimenting color on the rest and dark trim color for the doors and windows. If you go with warm tones, browns and or tans keep the roof as is if you go cooler bue/grey stones and color change those roof tiles to medium grey.
I would also add pillars where the walls dip in the middle on the porch to match the corners, it looks odd right now like they are missing. Put some potted climbing vines on the porch so they can climb the posts and as much greenery as you can fit in the front yard.
I hope that helps
