I like this timeless/classic style of shot.
I tried cropping as Kikashi suggests to see if it does anything for the image and after some experimenting, I don't think it did, I suppose you could perhaps tweak it a little on the right, but after looking and trying various selections, I don't think it needs it, I like it just the way it is.
Toning wise I am not sure as I have nothing to compare it with, but it looks good as it is, but to my mind, toning is a very subjective issue, some people like it and some don't, so if you like it then that is all that matters, it is your vision after all.
Very nice shot.
