good
Okay, for a critique.
The animation is extremely uneven in quality. Some portions are well done. For instance, the landscape shots are nice. Your creative facials designs are also pretty interesting, but somewhat hit or miss (the guy on the horse, for instance, looked pretty terrible). Your detailing of the internal organs I consider a plus, as it really does at a lot of depth to your frames.
At first, I found the violence to be excessive, but as it carried on it seemed to get funnier and funnier. As, what I'm assuming is, a parody of over the top and indulgent violence, I thought this really hit home. Every over the top slaughtering seemed to get more ludicrously amusing. It's the slow-down the really makes it work, though. I feel that some people didn't take too well to the violence due to the score, but clearly it's an integral part of the humor here so nuts to them I guess.
Now, at some parts it just looks awful and I think that's what really hurts you the most. Even during some of the better segments, the whole thing feels like it was done in some MS paint universe. Whether it be intentional or not, it hurts the overall presentation. I'm just going to assume that, as someone who is clearly capable of drawing decently enough, you don't need to be told which portions look good or bad, so I'll leave it at that.
The humor was solid. Some parts were funnier than others. I loved the sniper. I bits with the kings. Found it funny how you used the same silent frame of prosnorkulus during all the dialogue.
Overall, I thought this was decent, but if you could increase your line quality. Make your animation more fluid. Add some visual flair. Have a bit more consistency in the quality and improve a few other details I think you'd have something awesome here.
I rated 10 because I think this deserves a better score, but my actual rating would be about an 8.
