I really like it, her face is so fierce. I don't think her face looks like her although we don't know what she would look like if she were this realistic really, it's up to the imagination. There is something about her upper body that is off. I think it is her arms, they seem too skinny considering she has this big armor on. Also, the chest of the armor blends almost like the body of a man, it doesn't look like armor at all. It looks kind of like if a chubby guy with a gut were to suck in his stomach so much and so hard that it poofs his chest, like on the old cartoons when they hold their breath to walk tough like they had a bunch of muscles or something.
You are very talented and I love this piece despite its flaws I've mentioned, and reading your caption has thrown me into one of my Zelda moods as well. I am a HUGE fan of Zelda - I have the Triforce on my arm and everything.
Fix the armor to look more like actual armor, but have it fit her body a little better, and watch the arms because they look too long and skinny to me, but that may change once the body is fixed. Put some more detail into the whole picture for example, her dress. Show the beauty her dress itself holds. I've always imagined that it would weigh a ton having metal like mesh layered on top of soft fabric almost like her dress is made from armor, but still just a dress. You put so much detail and effort into your cation, you should have your art piece match.
Overall, you did a great job no matter what. And, hey, lets face it, it's better than what I could have done and I am no art critique. =) Draw more Zelda stuff!! I am waiting for Lake Hyilia stuff from someone! Pleeeease! I do think judging by your style you would be great at the landscape parts of Zelda, you do have the colors down almost perfectly. Keep it up!! =) More!!
