@robz I think I have played with this off and on all week. I tried to work on perspective and used a free crop. I think I have the edges better, although the middle is more off than before. At least I caused everyone passing to look up as I took the shot. Otherwise, they would just charge by.
Hi Shutterbug - I think you've made a big difference to it - it was always lovely but now it's also so well balanced and symmetrical. It looks just great. Thanks for not minding me mentioning it - I really like it when I get suggestions but I always feel a bit funny mentioning it if something catches my eye... Cheers Rob :)
