I was responsible for making the main zone trees in Eversong Woods. The design of this tree kit is based on the original trees found in Eversong Woods (World of Warcraft: Burning Crusade), as well as key art provided by the Viz Dev team (Gabe Gonzalez), and my own concepting.
I created a separate hanging vine asset kit which World Building could then set up to toggle on/off trees on an individual basis for more variety, and to stay true to the original zone trees.
We wanted to maintain the twisted trunk from the original trees, as well as the yellow, orange, and magenta gradient canopies. Red canopied trees were added to be used in the vicinity of Windrunner Village and to help designate the Horde section of Silvermoon City.
I also created the Lightbloom version of the tree kit, which you can view here:

The swirly tree roots are detached from the trees for flexibility in their placement, and are made by Cory Carrilio:
