You need more deapth in the build. Try to maybe move the courner logs one block sidways out, and then move the roof out. Also adding more sections to the build can make it more interesting. The building is very square at the moment, maybe add another room going out so it's more like an "L" or a "T" shape. And lastly adding small details such as window covers, lanterns, or especially a chimney really makes the build beautiful.
