I disagree; everytime I see Zelda fan works, they default to Minish Cap/Four Swords Link. Seeing something based on LTTP or the GBC Zelda games is a breath of fresh air. With that said, the head still looks awkward compared to the rest of the body. In this regard, it's mostly the proportions. You've got a more realistic body structure going on, so the head should be molded to compensate, sort of like Castlevania sprites.
Also, the scarf should have an outline like the rest of the sprite.
