There are lots of shots of George's Island and the Halifax skyline from this perspective lately because the island was just opened up to tourists. Here are a few more:
View from inside Fort Charlotte, looking toward downtown. Too bad they didn't take one looking out to sea which was the main orientation of the fort. The citadel, Fort George, was built mainly to defend the city from a land-based attack while Fort Charlotte, York Redoubt, and others defended the harbour. There are probably 20+ old fort and battery sites around the city.
A more complete view of the downtown skyline. Often you only see a small part of this in skyline photos. It also continues north and south a bit but you need a lookout point that is farther back to capture it (the Woodside ferry terminal area is a great spot for taking a big panorama but I haven't seen any new ones that capture the latest construction):
Zooming in on newer highrises that are mostly along Sackville Street. There is a "gap" here corresponding to the empty Skye tower development site (which includes the short 70's-like brown building that will be demolished), and then another corresponding to the Ralston Building site, a ~10 storey 50's building that was demolished a few months ago.
