Nice! Thanks for posting.
The short height of the Concord Towers (I counted 19 storeys) makes the Casino tower look really tall (I counted 25 or 26 storeys (note tall commcerial storeys in podium))
The standalone tower in the middle of the Concord project looks awkward - I don't like the "quarter round" shape. It looks poorly resolved where the curved ledges hit the all glass facade (in the last rendering). Maybe just take those ledges all the way around like on the stepped tower.
It would have made more sense asthetically to have the quarter-round curved facade face the other tower (but not from a privacy perspective), but the curves leading into and through the courtyard looks OK too.
Posted this in the "Colours" thread too.
Note the similarity of the stepped curved tower to the original Pacific Place lagoons concept.
Now its' just farther inland (and shorter).
