This is only a "template", it is NOT  for use on servers, as it may be considered indecent. I have made this ONLY to present as an exampl of how a male body should be shaded(Please remember that I am not a professional artist and I do not know how the male body is supposed to be shaded) It is but a try at shading.

I will use this skin for demonstration purposes in my shading tutorial (wich you can find here)
