Pros:

Colours fit in with L4D2 theme
Seamless design
Looks nice overall

Cons:

For some reason, this makes it harder for me to spot hunters O.o -0.5
Feels like I'm killing bronies :( -0

Conclusion:

This is really cool and even fits the overall theme of L4D2, but I don't like the sound pack.

Pros:

Subtle
Perfect placement of design
Glow in the dark

Cons:

Nothing

Conclusion:

Awesome, althought I think the Nurse Redheart one would, well, fit in better.
Also I'm on a reviewing spree. Yaaaaay

Pros:

Subtle, not too in-your-face
Blood effect is kept
Colourful but concise design

Cons:

Handle design could be better (move cutie mark to main handle) -0.5
More colour variety on the handle :P -0

Conclusion:

Really cool mod. Better than other mods which are too obvious and "noisy". Great job!
