I've always loved the poem about Aragorn, ever since I read it in Fellowship of the Ring when Boromir recounts hearing it from someone (I forgot who). I love how it's prophetic, and how it describes Aragorn and his personality, his destiny.
These pictures are perfect. You can see all the strength and power that he has, and yet there is so much fear in his eyes when he becomes king. Fear of failure, of weakness, of not living up to expectations. It just solidifies how necessary it was for him to take on that role, to return to his homeland and accept his heritage. Especially when you contrast it with Denethor's power hungry psychosis.
