Pros:

High-quality port
FPS arms
Face Animations
Hair jigglebones

Cons:

No Incap, though this isn't really a big deal

Conclusion:

Overall a very high-quality mod.

Pros:

Lighthearted and colorful.
Appeals to the intended audience, being the bronies.

Cons:

Design doesn't seem to be explicitly pasted on, to a degree. In turn, feels authentic yet not.

Conclusion:

This skin may not fit the whole apocalypse theme, but A LOT of good mods don't stick to theme and get away with it.
Honestly there's nothing wrong with it; part of the fun of mods is being able to make something so..."out there."
Giving the skin a low score simply because of a shallow hatred of its origin is immature.
