Really, mspaint is easy to draw. I can even say this after drawing on a computer at school with a really crappy mouse and I'm used to a touchpad.
Speaking of art, I did a piccie of Whitney
I used PaintShop pro for basically everything cept I did the basic sketch in mspaint.
Boy, the lineart was tedious though! PSP doesn't really have too many line options so I had to keep doing every line over and over till it achieved that width variation. And then I had to fill the holes so the paint wouldn't seep through.
I was lazy and didn't do cel-shading, just did regular airbrush shading. WAY easier!
