She became part of the forest and often didn’t realise how very long she stood gazing at the wonders around her.

I really like that little addition, it makes the previous description of the forest come more alive, more visible to the mind.

Katherine shook her head in anger and the clearing wiped from the surface of the world. Katherine gaped at the destruction she had wrought.

A fantastic way to show us her progression in the realm of magic. A fantastic addition. I can see her standing there jaw agape staring at what she had unknowingly done. Great scene, and great addition to fill in even more of the character and the magic.
