This illustration of Bilbo is one of my FAVORITES. There's something so fantastical about it, like I can feel the wind blowing through the grass and flowers.
This next one shows the scene from The Hobbit when Bilbo and the Company are riding on the Eagles. Look closely at the line work in the feathers and clouds, it's amazing!
Another one of my favorites is this piece of Éowyn and the Witch King. It's a dramatic scene, and I really love the bright colors and flowers on her head, it makes it have a different feeling than other depictions of this moment. Like things may actually take a turn for the better because of this victory.
