some spoiler...

2 years ago River and I wrote a small tutorial about painting woman skin. River translated and published it in our Serpentarium. If you interested you can find it here http://serpentarium-painting.blogspot.com/2012/08/a-sample-of-woman-skin-tutorial.html

So what I wont to say - second tutorial (with anoter strange colors :)  ) will be ready soon.
