Nice photos, HX. Just a few observations:
1. It seems like overkill for ASU to put their logo/letters on every one of their downtown buildings--we get it already they have a new campus. (Especially tacky on the new Cronkite building, imo.) Why not just some discrete signage at ground level? NAU has done this quite nicely.
2. As much as everyone hates the Sheraton, there are plenty of fairly recent convention hotels in other cities that are about as drab architecturally. (The one notable exception I can think of is the new JW Marriott/Ritz-Carlton convention hotel going up in downtown L.A.

Also, can someone explain why the north and south rooflines on the Sheraton were sloped in opposite directions rather than being symmetrical (i.e., the south roofline slopes down from west to east, but the north roofline from east to west) ? As other forumers have already pointed out, this leaves those big rooftop utility/elevator boxes exposed on the west end, which is really unsightly.
3. Hasn't the city come up with a name, or considered having a naming contest for the new civic park? (Hopefully not Central Park, for obvious comparative reasons.) If they don't do something soon, I can see once that main artpiece gets fully installed, residents will start calling it "Jellyfish Park" or something similar, and the nickname will never die.
