Really great work - In particular the composition in 2 and 3 is amazing. It certainly is a shame that people feel the need to chase you away just for taking photos. For anyone else considering taking photos in a cemetery I'd say don't be put off by what other people might think - you're not being disrespectful unless you're disturbing the privacy of mourners, taking shots of a funeral service etc. That the guards want to chase you away says less about you and more about the complete inability of our culture to deal with death that means we think cemeteries are best avoided at all times, and that anyone who refuses to do so must be abnormal.
