Help making the exterior look less bland?

Any tips on how to make the sides of this house look better? I’m planning on making a cherry grove village with houses in this style (I used a tutorial for this specific one to better understand the shaping) but don’t know how to make the sides and back walls look more appealing!

I tried indenting the windows with stairs but I don’t think it’s enough. If it matters, I’m going to use bamboo planks for the roof instead of the spruce used here in the test world!
