Here's the lining and coloring tutorial. I just thought that it would make more sense to do this one first.
In case you don't know, saturated means more colorful (bright hues) while non-saturated/desaturated means paler or grayer (dark/pale hues).

But, how do you get the smooth lines? Is there an option for that or is your hand that steady?
Also, do you make the sketch in PS as well?
