I don't think I've commented on this before, but, as a life-long (over 50 years) LOTR and Tolkien fan, I can't resist. This is good, and well drawn in a style similar to Tolkien's own. But, I have to admit that I see Treebeard in a different, and darker, way. That does not take anything away from this, which is worthy of the Fave I give it.
That's okay, we all have our own interpretations! For me Treebeard appears (especially in this part of the book) a character with both warm, comical and on the other hand deeply profound and sad aspects to him, which is what I tried to depict here. (Not sure if I fully succeeded though, in my own opinion, even ) But I know my style in general even is often too juvenile (or "children's storybookish", nicely put) for some, whereas others appreciate it exactly for that reason. I can definitely understand your viewpoint about Treebeard. Thank you for sharing your thoughts and I'm glad you like the painting otherwise!
