Well, I must say it's a well done castle.
However, the only thing I liked with it was the shape of the outside. Very well made and creative.
The inside is very dull and boring + the fact that there no interior walls.
The entrance hall is first of all very empty. The walls is plain with nothing sticking out, other than those banners, which makes you see that the room actually is a square. I find the guards quarters pretty strange because it only uses wood. And it's the only room that uses wood for other things than for decorations. Anyhow it looks pretty and more interesting with the use of wood in the castle, so that would be good to increase. The throne room needs more decorations and details. Especially on the wall behind the throne. The windows there looks strange and the beams is waaay too thin. Looks like they'll fall any second. The dining room is one of the worst rooms. Really boring and also random. It needs more stuff on the walls. Stone pillars, decorations.. I don't care. Just add more stuff.
Improve these things and it'll be great.
Love the build, keep on buildin dude.
