Indeed, a very good shot! Shame about the crane being idle, though, but that's 'progress'!.
There's a great angle you might want to try, if you can get permission. The Co-Op building by the end of the Kingston Bridge has that tower - there is an interior staircase that leads to a small gallery on the outside of said tower, from which there is a great view over the bridge and towards the Daily Record building - unless I get confused with geography again, but I think not - which I once used for, I think, Clydesdale Bank advertising. Worth the climb.
