I began this abstract drawing with thicker lines using calligraphy pens, beginning with the greens and orange. Then I used the narrower tip of the pen to draw some medium-thick black lines, and finally red and black fine-tipped pens for filling in some of the spaces with closely-spaced "doodles" for texture. I also used a pale green brush pen to fill in some spaces. The result is kind of wacky, but I like it.
