This is a sketch exercise I try to do daily to stay adaptable ( perhaps robotic ) using the Cintiq tablet - since I am still not used to the drawing surface. I sketched with a regular, standard, round brush.
I am in the current process, trying to learn how to use blender for sketching, painting, and 2D/3D animation, but the software is not that simple and is a compound of many long processes that take teams to do, but again - willing to learn this information from anyone willing to spread their 'Blender' wisdom.
Approximate time = 40 Minutes ( or less )
