"Leaf"
I got a "leaf" photo (1144685932tJM23P.jpg) from unrecalled site. I started tracing the stem and the leaf using the pen tool and convert point tool.
I had a hard time tapering the parent-stem from base to tip; more so with the child-secondary branches. BTW, I used stroke with the default 1-pt round brush.
On next version, I'll be using my own custom brush to create taperings. Or I'll do the hard way; making tapered shapes with black fills. I don't know.
