I am not sure if these have already posted, but the architects' website (lydonlynch.ca) has some nice renderings of Waterside Centre:
Back in 2005, Serge Lacasse took a great photo of the "canyon effect" down Hollis Street:

It would be interesting to see a new photo once Waterside goes up, since that will make 3 new buildings since 2005 -- Salter's Gate and the Vic apartments are the others (the building on the left in the distance is the Waterford, which is somewhat new as well). Had the United Gulf towers gone up, they also would have contributed to this view.
