You've got the DAZ textures applied and they're in the Textures/DAZ/Characters/MilMan folder. Both the standard and Hi res M4 DAZ textures aren't much chop and you'd be better off with 3rd party textures for him.

Whatever texture you choose don't forget to use the EzSkin python if you are using SSS. The decent M4 textures you'll have to pay for, but EzSkin if free.
