Nice restrained hand on the verdigris effect - it's all the rage right now, and I think people tend to overdo it. You've got it in spots that you'd expect it to collect, and done in an appropriate amount.

You nailed the weathered effect! 

I love the patina. You've placed it well! Try to put a bit more info the shading to give the model more depth. It'll look really bold

Agree with the previous comments here, the patina is lovely. Going to have to try some on a model of my own here soon
