Needs alot of improvements
The beginning started off good. However there were a couple of things that need to be fixed before you should get your series on the roll. First off, its probably best that you add wings to Navi. I know you mentioned somewhere that you think the wings look stupid but the sad fact is that unless you want fanboys and girls niching at your heals over that one detail over and over, you may want to consider it. Also, Link looks terrible. Remember, he's one of the main characters, aka the guy people are going to look at throughout your series, aka the guy people are going to concentrate on.
I think its because there is none or barely any shadowing. If you can do Navi, than shadowing should be no problem. If it is, than go to a shadowing tutorial here at this site. It makes a big difference. Also, you made his face a little too square. Good for castles, bad for people. It needs to be more rounded off. The same goes for your eyes.
