I think the scale makes the concept of hugging as a literal physical act difficult to get across no matter how you do the posing. How can you hug something that big? The tree is a prop for whatever you want to do with the model, but that's about all I can see it being.
It seems like scale is a problem here. It feels more like the shear size of the tree is the subject and not the model. She provides something to establish just how bloody huge these trees are, but she's not the subject per se. You see pictures like this in travel\nature books and text books.
If the subject of the shot is the young lady, then make the shot about the young lady and treat everything else like as a prop or background to her. Heck, you could put her in a tu-tu, give her a wand and hang a pair of little wings on her and that would definitely make her the subject if you want to keep to this inclusive field of view.
Much tighter framing would have worked, so you could crop this image to similar effect.
Right now, I see this image being about size.
You can hug anything of any size, it does not necessarily mean you have to get your arms all the way around, if that were turn I'd never get hubbed
. I think the arguement is that the models left arm is not touching the tree therefore it cannot be a hug, it is half a hug at the best,
