Recommended tutorials for making realistic Sim Skins?

[CB2001]

Now, I have opeu's and HystericalParoxysm's tutorials about how to make realistic Sim skins for Sims.  I was wondering if there are any other tutorials on how to make realistic Sims skins if you recommend it.  Just let me know, guys.

by realistic, you mean with all the bits and pieces? (and you are talking about literal skins, not clothing, is that correct?)

I'm talking about the Skins for the character, not the clothes (you know, how you can change the skin color?  Those are skins.  And some of the best Sims available have customized skintones that have the actors/actresses face on it).  You know, the Skintone section is what I'm talking about.
