Here's drawing number 1 of my experiment, the wonderful Kasumi Tendo from Ranma 1/2. This was the first time I used the stroke path function. Initially I did multiple sketches free hand with the pencil tool. Then the stroke path was used to create the crisper lines. Gaussian blur was applied at the end to remove a lot of the jagged edges. The shading was done using the airbrush and smudge tools.
Also I want all my drawings done entirely on freeware programs. This one was done using GIMP.
I watched the first 5 minutes to learn the stroke path tool here:
