alright, moving away from the style crits, here are some thoughts about the drawing itself:
First, a question. Not just for you to answer, but to think about: Where is your light source? It looks like you want it to be directly above Link, but there are a good few instances of pillow shading.
I think the pose is really weak. He's just kind of standing there. But it's not just normal standing still, relaxed, it looks like it would be rather uncomfortable to hold that stiff pose, especially with the feet so close together. It almost looks like he's about to fall over to his left. It might be something that's difficult to change at this stage, and probably something you don't really want to change, but it's something you can at least learn from.
This one's an anatomy crit, so you might regard as me not quite agreeing with your style. I feel his head's way too big for his body (it aids to his off-balance look), and his mouth is small and a little low.
Now, some things I like:
I like the big eyes. They aren't quite Manga eyes, but neither are they the eyes of the more realistic comic-book style you referred to. I can't say why, but I feel they work.
I love the shading style. Dramatic in some spots, softer in others. I feel it works best on the face, with the eyes and everything. It really gives this piece a UNIQUE style, and that's something I admire. I can't wait to see it finished.
