That's kind of a loaded question. I don't Skin Studio to be that hard to learn, but it's hard making a really GOOD skin. It's like any other program, the more you use it, the better you become, and the more you understand.

I'm a night owl to begin with, but lately, I've been getting to bed as the sun is rising, because I just need to "fix this one little thing" -- and either it doesn't come out the way I want, or I'm so pleased with what I've done I can't stop.
