these are not my skins
If you don't know how to paint a face white and black there's really no hope for you yet, just play with the features for a while and get in touch with your inner skinnner. Also, ICP sucks, personal view that's shared by everyone.
personel view not everyone thinks ICP sux XD besides i tried using linear brun on it and tht does no justice should i use image ready or photo shop
Photoshop is what the pros use! And you should use a paintbrush with whatever color you want with about a 20% transparancy on a feathered brush and just layer it up to what you want. If none of that made sense to you you should familiarize yourself with the program first.
