Just a quick thought- to me, the lighting on the nether creatures looks a little... white, don't you think? Looks more like they're lit by florescent or sunlight than lava-light. Have you tried adding a little more orangey-red?
p.s.- I'm basing this observation on the screenshots in the OP, which I know have been around a while, and not my experience with the current textures, so I could be completely wrong about this.
The red fog in the nether should fix this, make sure you use MC Patcher to enable the Custom Colours!

Pale creatures would make sense though.
They're in a cave with no sunlight all the time.
The fact that they're bright white is probably because of the lighting.
MC Patcher allows custom lighting colours if the pack's author wants to fiddle around with that.
Tobiwan could take a look at Misa's realism as an example for custom lighting colours (where torch light colours are seperate to natural sunlight and moonlight)
Tobi has used the Custom Colours quite a bit in the latest version; and the torch, moon and sun light are a part of vanilla, implemented in beta 1.8ish
