It's not watercolor, it's soft cel CG and I use Painter to do it. I also do digital watercolor and it looks heaps different XD. Depending on what effects I want I do my CG work in either Painter, Photoshop, and OpenCanvas. I've been doing CG like this since 1999 :D I had five years of art school in college, and ultimately what makes for good digital coloring is pretty much the same that makes for good traditional coloring: an understanding of how color describes mass and an understanding of color and color theory in general.
So yeah, I am an old lady XD.
