A sheet of 4 different types of cyborgs.  I used the same line drawing of the human figure and added mechanical parts, but I painted everyone separately for the practice.  The first is the most human having only a mechanical arm and knees along with the left thigh.  The second has much more cybernetic parts.  A claw hand, an entirely robotic leg, most of the head is now machine.  The third is more balanced between human and robot. Both the arms are robotic, half the head is robotic, and the legs have plates on them for armor.  It's left arm is also an electricity based gun.  The last one is also highly robotic.  It's more streamlined and has a more futuristic quality to it.
