It has a nice classic look to it.
I agree with two previous comments. There seems to be a barely perceptible lean to right, and if the tree trunk were one of those lighter dried out, almost bone-like ones, it would really set it off from the background scene (which is very attractive).
Is there any chance this was a color capture converted to monochrome, and that adjusting the RGB balance in the conversion would lighten the trunk? It looks like a tough outline to dodge without obvious transitions showing up.
Maybe relatively minor changes could take this one from very good to great!
