Oh, no no no! Why does he look like a leprechaun?! He's supposed to look evil and intimidating... And his body is not this big, and his head isn't that small.... I am trying to appreciate this for what it is... a picture drawn by someone, but I cannot look at this and say it is Ganondorf.. and it's not Ganon, he is only called Ganon when he transforms in Ocarina of Time.
You did get the colors perfect, though.
