I think you may have got the tonal processing right.
A very small nitpick though - I wonder whether cropping the sharply delineated trees on the right may help concentrate attention on the spectacular oak.
All in all a very fine image.

Thanks, Tony.
It's already relatively heavily cropped, bottom of the frame, to get rid of a lot of clumps of grass and sort of center the tree, and I like the trees in upper frame right, but you're quite correct: the ones directly to the right of the main tree are distracting.
I'll give it go and see how it turns out.
