Human character texture reference

Hello guys, I finished my 3D human model and now I want to project texture on him, I found a lot of nice male faces skins to project on my character but, is legal to project somebodies skin on my character? Or I must find some site with free human textures, if is the case, anybody knows any site wich provides it? I only know: http://free-textures.got3d.com/index.html but I don’t like at all any texture there.

check the first thread in ‘Materials and Textures’.
and you can make your own with pieces of other textures and photos.

Wow, thank you Secrop, very useful.
