Dark and Dramatic
Well, first off. Excellent drawing skills. I had to favorite this because of the loving attention to detail, which goes a little more than skin (or in this case paper) deep.
This picture I find is a much darker, grittier and more realistic view of Link and Navi than the games portray. Besides that though, it is also quite dramatic. You show the warrior's strength with the blood stains and dirt and shading. You show his heart with the gentle cradling of Navi, the only one who was alongside him as he fought through all those battle fields. Sure he had allies who would be there occasionally, but through the entire trudge across the darkness of Hyrule, Navi was there the whole time.
Well I got a little off track there, but I'll finish by saying this is a beautiful and excellent piece. Very well done.
