I think that's the first time I've seen a traditional interpretation of the "crown of leaves and berries" that didn't look like a bad bridal headpiece of just plain silly (every "Ghost of Christmas Present" picture I've ever seen). As it is, you somehow manage to pull the incredible dignity out of something that could be otherwise ridiculous. And I love the clean lines of his profile.
And this approach is so logical. It's one of those things that I dislike about the Hobbit. In the Lord of the Rings, an old man with a beard and a hat looked like an old man with a beard and a hat. In the Hobbit, a Dwarf with a beard and a hood looks like Asterix with no beard and no hood but an arsenal of weapons, and an Elvenking with a crown of leaves and berries looks like a... drag queen with a fence on his head...?
