Nice Concept.
This is as great as Nintendo's arts, and you even added details such as that little armor under his tunic.
But, if I'm right, this is the Twilight Princess' Link, isn't it? If is, then he should hold the Master Sword with the right hand, and a background would make the picture better.
Anyway, that's just awesome. Those little mistakes don't spoil the picture at all. Good work!
