this is a useful break down. what program do you use? I find I have a hard time making smooth lines in photoshop and the fill tool always leaves a thin empty line.
I use photoshop only :)
Wish I could color like the 4th or 5th picture. I never know how to get it done like that. I always do it like the 3rd picture..
It's funny how the colors primarily become warmer as it escalates.
