… note the small side sketch that shows what will become Uhura’s station opposite the main view screen indicating that, even at this early stage, the turbo lift alcove is in the same place we will come to know it to be.
Note also the partial dome in the small sketch to the right, which “might” suggest the smaller scale dome for the early 540 ft. version of the ship?
On the other hand, since this doodle is evidently just a quick side sketch and thus not drawn to any exact scale, it might not be wise to infer too much from it.
