Your favourite place in London

Hi everybody! I'm participating in a photography contest and I NEED YOUR HELP! I'm looking for people from different countries who would like to pose for a portrait in one of london's iconic landmarks (could be one near your house!) and tell me what is it that you love more about london... The pictures shouldn't take more than Protected content ... but I'm too shy to approach random people in the street! :)
Thanks a lot in advance! Flo x
