I found a site that has a bunch of Tolkien art with drawings/paintings done by JRRT himself. Unfortunately, I couldn't find one of Treebeard done by Tolkien. Here's the link: Art Gallery

That's an interesting site. Tolkien seems to have quite an eye for composition, you'd think that if he'd devoted his life to painting instead of languages and writing, he could have been great at that also.

This one in particular, of Old Man Willow, strikes me.

"Unfortunately, I couldn't find one of Treebeard done by Tolkien."

Tolkien probably had trouble "visualizing" him.
