Asian Castle

I tried to make Osaka Castle, but I failed at the second floor. So I just built it in the way my hearth told me to do. Joking. To me it looks more like a crossover between the Military Academy from the Japanese Home City and the Chinese and Japanese Castles (all of them from AOE 3). My friends complained again about my ugly style of making stairs inside, so you must build the stairs to each storey. I made only the entrance stairs. You can place lightning sources wherever you want since I forgot about them :)
You must have Biomes O' Plenty to make the roof and the floor
Enjoy!
PS:It's 55 blocks tall from the base so you might consider building it on plains. If i remember right, the height limit for buildings was +256

PS2: here is how the Osaka Castle looks, if you're curios https://www.google.ro/search?hl=ro&tbm=isch&source=hp&biw=1326&bih=629&ei=8DlGWsKQMer76ASx34zQDw&q=Osaka+Castle&oq=Osaka+Castle&gs_l=img.3..0j0i30k1l9.220.2206.0.2328.12.9.0.3.3.0.117.822.8j1.9.0....0...1ac.1.64.img..0.12.841....0.vVsnpms-6Xc
