Using the same technique as before on the body i desaturated all the layers and started to manipulate the brightness and contrast until i was happy with it. This is very much a trial and error type of process switching between the two applications Photoshop and 3DS Max.
Here is the Normal layers in Photoshop before i flatterned them all and applied the Nividia NormalMapFilter;

If we now compare what it looks like with and without a normal map i only wanted it to be very subtle around the face area but as you can see this does add abit more realism into the face.
