You got a superb expression on him! It looks like he's thinking, "Well, it's going to be tough outside, pity it's necessary, but I'm not going to miss this place, at all!" The colors and details of his costume and curves of Gwenhyvar are all evocative, I love it!
Beautiful. I love the depth of emotion and determination coming from his eyes. The colorfulness of the city he left behind against the darkness of what he is about to enter is awesome. A besutiful piece of art it truly is.
