SOLOMATION Cy Porter, the owner of the mentioned website demonstrates how to draw a hand from the thumb perspective. He says that this tutorial is to bring out the thumb's measurement and relation to the rest of the hand. First he draws the palm and the wrist, giving as a square shape to the palm. The he draws the first joint of the thumb saying that the center point of the line joining the knuckles and the wrist and the center point of the thumb's first joint forms an arc. Then he draws the second of the thumb saying that it is in the same arc as the line of the knuckles. Then next he says that the tip pf the thumb is in line with the arc of the second joint of the other fingers. Learn that the arc of the knuckles is pretty smooth and falls of at the little finger end. He says that the first joint of the index, middle, ring and little fingers fall in the same arc while the arc slightly falls off at the little finger end. Then he explains about the arc of the second joints of these four fingers. Learn that the tip of the thumb and the second joints of the index and ring fingers fall in the same arc while the second joint of the middle falls above the arc which means that the middle finger is longer than the others. This arc too falls away after the ring finger indicating that the last finger is pretty smaller in comparison to others. Thus he gives you an idea of the finger alignment. He also says that the ring and index fingers are not identical but very close and fall in the same line. He then says that to start with, the palm shape can be made little blunt at the corner where the little finger will be. He also says that you can try this out in a 3D space to make it more effective. Cy then finally signs off saying that he really enjoys doing this animation stuff and you can check out his animation work at his site SOLOMATION.
