Personally i wouldn’t say I’m a great builder however some advice I’ve been given in the past was to create depth in this case you don’t want a flat wall you could achieve this by exchanging some of the cobble blocks for cobble stairs, pushing the wood pillars out of the wall by one block to frame the build together and you could link them at the bottom with fence blocks it also wouldn’t hurt to vary the cobble textures or to create fixtures outside your windows for example by using dirt and upside down stairs or something similar to create a flower fixture you could also use fences to box the windows and create a focal point of sorts with that.
