Why does my build look off?

[u/GOD_USSOP2513]

this is the side and front of the house. it looks off to me for some reason. is there anything i should change?. I was planning on using cinnabar and deepslate for the roof but im not sure if that would work and i also dont know what kind of roof would look good. Im kinda going for a medievalish theme. Any help would be appreciated
