Camera Experiments and Filming Locations

Today I practised filming panning shots 180 degree in Central London and learnt which positions/specific places on Oxford Street would be best to film with the tripod(for a steady shot) where it was less busy/less crowded - Marble Arch. I thought this place would be best to film the other side of street art which is not graffiti, as street art could also be simply art on the public streets; sculptures and architecture.
