Please don't take this the wrong way, but I believe his face requires quite a bit of work. As it stands, Link looks petrifying and slightly constipated. The constipation look comes from the bevel around his mouth, making it look like he's sucking in air. Equally his eyes are...alien-esque. They seem to be too close together and tilted upward at a strange angle.
Regardless, the rest of your model is great and you're doing swell so far!
