I think you would benefit from representing the hunters as more than "evil people." I understand that commonly made choice, but when you represent the villains as real characters with independent traits and actual depth, giving some insight into their motives, you can do a more effective job of showing people WHY their choices are wrong. If they're just mask-faced, evil, red-eyed dickheads, then you don't establish that connection, and your whole story just feels like it's ignorantly pushing a one-sided ANIMALS HAVE FEELINGS TOO agenda. You've drawn hunters in the past as just people, so I'm sure a portion of your choices here had to do with your own stated desire to go with a simplified animation style, which is fine, but that Disney-style BAD PEOPLE ARE BAD method never tugged on my heartstrings I guess. Also, when the one hunter's eye faded out instead of closing shut, I was like "Heh, I guess they were all terminators. That explains it!"
Not to say an anti-hunting agenda is why you made this, I'm sure it's not looking at your past works, but it still gives off a closed-minded feel that I think you're probably better than. Not that I don't agree with the point, though. Shooting animals for yucks is a bit of a dick move. I just think a story, especially a decidedly dramatic one, benefits from both sides seeming potentially viable to the unbiased eye, with one side doing something that someone may or may not regard as going too far. Melodramas where villains are clearly villains and heroes are clearly heroes with no gray or understanding for the other shoe are a little passe.
Don't misunderstand me though, I think it's a great piece. It's cool to see your improvements and you did a proper job of building drama and tension. I would hope you to be having a great time with viewers since foxes are trending right now and you were all about it "before they were cool."
