For some reason, in my mind I had been envisioning the area around the base of the ship to be water. Maybe that was just lingering memories of UofE. In the video I see its just flat concrete with a planting bed surrounding it in a triangular shape. The back side has a walkway with a gate. There is conduit sticking up from the ground which I assume if for lights to illuminate the ship. So what will this area under the ship be used for? Overflow queue? Special events area (Nova Corp desert party)? PhotoPass location?
There was definitely concept art with two small circular pools flanking the ship. This would have gone a long way to make the pavilion feel more like Xandar to me. In the movie, (and Lego Avengers games), water pools are a signature piece of Xandar's architecture. I really wish they would have made the final cut of this attraction. There's also concept art with plants under the ship, so I'm sure we'll see those go in once the ship install is complete.
