I've been drawing subjects with hair that I like. I'm more comfortable with regular curves and lines. Natural curves, like hair, leaves and grass are something I'm practicing.
The top left panel is a freehand portrait of a Sheep with interesting curly hair and horns by Wet Sulky (a favored Artist)
The bottom left is my Beverly (purchased from Kiarrafennec) in a redraw; I pushed her hair behind her face floof on the stage left side, and turned her ear to mirror the other.
The right half of my page is my original drawing of my memory of a spectator perched on a fence post watching a youth team practice at my local park; she had simple flowing hair.
I do an outline and then some hair lines for flow and then shading with my charcoal pencils.
