Exactly, that's what I thought as well. The actual description sounds like someone describing something without visualizing it first. "It's got a lot of lines. People like lines? Ok, good. It'll have... fifteen converging lines. That sounds like it'll look good."
I basically ignored the guidelines as well... that central sphere really bugs me.
Also bear in mind that the design was overseen by Miles O'Brien, so I took the angle that the Chief basically redesigned DS9 after years of dealing with faulty systems and architecture, so he likely fixed a lot of things only9 he'd be familiar with.
Mostly, I just wanted something that wouldn't look like... a sphere with a bunch of gray rings wrapped around it.
