So I'm a total n00b with Paint.Net As a matter of fact, this Is the very first program I have ever used (i.e I have never used photoshop, Gimp, ect) I am, however, an inspiring anime artist...And though i'm only 16 now, I want to do something with my drawings when i graduate next year. So, I was wondering if there were good Skin coloring/Hair coloring Tutorials out there...I have looked but I can't find any good ones. Thanks for your help, Kriss
