I dunno, I feel like if it's important enough that your character be feral only it'd be one of the things you'd stress when you send the ref. Even if it's on the ref sheet itself, I'd always stress any important factors that must be with my character. While the artist ignoring you isn't good and they definitely owed you at least a correct feral piece, I feel like you could've been a little more understanding in that the artist's English is lacking. You weren't gonna get anywhere with long paragraphs.
