Nice tower! Maybe lower part of the buildning should be more "urban", made of stone, because thatched roofs and farm-like walls aren't combined with such advanced race as the High Elves (imho, of course).
Looks quite cool, but the border between tower and house bothers me.
Have you though about adding a clear border to it with some additional vertices,
so it look more closed and not as if the house clips with the tower ?
