Hey Mastone,

Have a look ar DrJulians Texturing tutorial as I think your spec map does add to him but not in the way I would have expected, for example his ears are not as shiney as what youve got them, plus the material looks like it could do with a tweek as its not shiney where the light hits the bits on the spec map.

Looking at the pics you posted as ref, the spec is really promanant on the top of the head/forehead, the lips and the tops of the ears.
