Today i finished the main hall and the inner wall. Then i continued with the outer wall, but figured out after building the 4 towers that i made a mistake at one point or another, because it was 201x200 blocks of an area in the end. Beside that everything worked out fine. Because the inner things aren't symmetrical it doesnt matter that the walls were one block off. After finishing all that stuff i started making all the inner things, a forest, a spring and a farm were the first things i did. The rest of it i may do tomorrow.
