Yes hello. Step one is not done, nor approved, and you have already started detailing the first hall. Wait until the overseers have given the ‘official’ OK. Even though all halls their purposes are currently marked, I think that the plan is still too rough on the edges. I’d like you guys to add wool to mark where pillars are going, and also how tall the arches are going to be. Try to be innovative, not lazy! Don’t go for the predictable grid-like arches like these (especially in the first hall which is meant to really impress people), but go for less conventional designs like this one Guan did in Bizar.
Same thing goes for stairs and hallways and how they turn. This stair, in addition to not aligning correctly when converted to actual stair blocks a bit further up, is a bit boring. You could make it more interesting overall by curving them in a fashion similar to this design style (though upscaled)
Also, think of how carts get down to the first courtyard, the stairs there are currently too steep and the turns are too sharp.
