FIGURE 4. Now things get a little trickier as we'll begin to lightly pencil in the divisions of the fingers, and we'll refine our thumb just a bit.
The thumb: This will only be a minor tweak. You'll simply be retracing your steps from the lower right corner. The only difference is that once your thumb outline touches against the bottom of your rectangle, you'll begin the top part of the trapezoid earlier, making it the top of the thumb. You will not be closing the top of the trapezoid this time (see figure 4).
Dividing the fingers: The fingers are pretty similar to one another, but the pointer finger and middle finger tend to be slightly wider than the other two. When you close your fingers and make a fist, you'l probably notice that the bottom ends of the Proximal bones tend to jut outward a little more than the top Proximal ends (knuckles). The middle finger tends to jut out in front of the other fingers as well. This varies from person to person, but generally the middle finger does protrude outward a bit more than the others. Because of this, we'll need to compensate some in the drawing. How will we do this? We begin by dividing up the four fingers via a series of vertical lines that start from the bottom of our original rectangle. We won't make these lines completely vertical. We'll be giving them a little slant (or lean)to compensate for the way the bottom of the Proximal bones protrude forward. These slanting vertical lines should rise upward to about three-quarters of height of our rectangle (see figure 4).
Note below (figure 4) that we have done something a little different with the dividing line between the ring finger and middle finger. Starting from the base of the rectangle I have chosen to slant the division line the oppose way at first. Then, only a short distance away from the rectangle's base, I reverse the direction of the slant, leaning it more like the other two finger division lines. When you're done with this line, you should have a shape that is not unlike a hockey stick shape. I should note that the tilt of this vertical line is a little more dramatic and steep.
FIGURE 5: By now you should be seeing a fist emerging from the framework. We have only a few steps to go at this point. We now will need to draw in the base of the palm as it connects up with the thumb below our rectangle. Then there will be some folding skin on the outside of the palm, just beyond the pinky finger to address. These areas won't need to be exact, and for now, basic shapes similar to those below will work as good guide lines:
FIGURE 6: Okay, your framework guidelines are down. Now what's left is to round out the fingers, and indicate the knobby shapes of the knuckles. Just remember that the middle finger's knuckle has the highest pinnacle, and don't overdo the shape of the dipping curves between knuckles.
You can now start drawing with a darker and more permanent pencil line. You should now be able to use your own hand as a model to fill in the necessary details. Just remember that human fingers aren't square. Flesh covers bones and ligaments forming rounded areas, and these rounded shapes are important in drawing credible looking
