It's the other settings you are using that are bogging down your render time. I'm half way through the final render pass on a similar sized render and it has only been 10 min. Take a look at my render settings on previous post. 

I'm not a fan of procedural bump maps...esp up close. But that is a personal thing I guess. When I get a new character morph/texture package I always make sure to give the bump map some love in Photoshop to fix stuff. Usually they just make a black & white jpg and forget that the dark eyebrows make a dip in the bump instead of a hill. Other times the vendor will just invert the whole map to make the eyebrows and moles correct but then you end up with the cracks in the lips pop up like veins.

Looks like you got the shade part down! I would say that there still is a disparity between your texture map and the shader mask. If you want, send me the texture map that you want to use and I'll make a mask for you.
