The wood texture felt a bit noisy to me, so I tried my hand at cleaning that up a bit. I'd recommend focusing more on the whorls of the wood, and how the light shines on those, rather than on trying to create specific texture.
I rounded out the face a bit, as the jawline felt extremely cartoon-y compared to the rest of the image. I added a reddish-purple to the lips, freckles, and eyeshadows.
I increased contrast on the hair and other foliage, which I'd say is something that you can take or leave since it does dramatically change the overall feel.
Anyway, hope this gives you a few new ideas!
