On the texture set I use, most of the skin area is about 58,58,58 for specular, which is quite dark, you are probably getting quite a whitish specular map.

 

attached - same scene with light moved to 45° x 45°

I also slightly reduced the specular

 

LatexLuv I never stop playing with materials :P
