The house itself is not symmetrical. Symmetry plays a very big part in builds as it keeps a professional standard to the build, which is what our build team looks for. Secondly, don't use more than one wood type in a build, as it is painfully obvious, and makes it look a bit out of place. Thirdly, don't use clashing block types - bricks and cobblestone clash very badly, and with the block palette, I'd recommend to follow a block palette consisting of dark-brown and greys (cobblestone, spruce wood, brown stained clay, andesite, ect).
