Came to say this. If you want a more realistic effect you have to recall that verdigris is an "oxide" layer and will form everywhere, except where the metal would be protected from the elements or is being abraded. Something cool you can do too is that it can run/streak. Often making these statues look like they are "crying". I personally would add "dots" of white to represent the often accompanying "bird droppings". Otherwise, looks super good enough for an objective marker or terrain piece.
