Symbols of Sydney, with some climbers!

My last day in Sydney and yes once again I went to the Opera House. However today I wanted to capture an image that the world would say, 'this is Sydney'. Hopefully this is it! I mean surely you can't get more iconic then the Opera House & the Harbour Bridge in the same shot!! But what I like about this photo is the people you can see climbing the Harbour Bridge (look closely!). I think they contrast with the clouds nicely. What are your thoughts?
