How to draw hands. By Giulio Porta 2012.
If your hands look like rubber gloves, or those of Mickey Mouse, and if you are taking one of my classes, you'll be expected to do better, regardless how you may feel about you current level of ability, you'll have to improve the drawing of your figure's hand. It's a course requirement.

Aside from the rubber hand look, another mayor problem which I see constantly is that of a hand which has fingers attached to its wrist, for some reason the palm is not there. I hope that this tutorial will help you in drawing better hands. This is not going to happen by doing a drawing or two, how many drawing you'll need to do that will depend on you.

The drawing you see here were done with a graphic program using straight lines, it doesn't matter that much what you are using as a medium. What matter is the process, the sequence of steps and what you should have in terms of anatomical components.

Drawing fingers.

If you look at your fingers you'll realize that they are made out of three articulations, therefore it will make a lot of sense if all the fingers you'll draw from now on will be structured to have three articulations. Look at your hand again.

Begin by drawing several fingers from different angles.

Don't worry too much about proportions. Proportions will be address later, in the drawing of more hands, right now train your brain to think about each finger as having 3 articulations.

The 3 articulation will prevent the "rubber glove" syndrome that fingers drawn in one piece seem to acquire.

Ad nails to your fingers, each nail give each finger a sense of direction. A finger back view will have no nail.
The palm.

The palm is a cross road where the wrist and fingers merge, or branch out.

When drawing the whole hand it should be drawn first, for now draw it like a flat box with 3 visible sides. Again don't be too concerned about proportions, you want to be comfortable in performing these routines without concerns directed toward achieving proportions instantly.

This approach will also help you in thinking about the hand as a 3D object.

Attaching the fingers to the palm

Begin with the finger closer to you, meaning the one that is in front of the others. Draw it in 3 parts. Look at your hand, please! Don't make things up, if you are looking at your model (your hand) don't loose track of it, if you do your drawing will soon deteriorate.

add the other fingers one by one, work slowly and methodically, preferably life size, if not do that for the next drawing.
Draw the wrist and contimue the drawing into the arm, run that off the page as there was a person out there.

Clena up the edges with white paint (acrylic) by erasing or by outining the hand with stronger line. Or with all of the above.

Fill that hand with color.

How much refinement is brought to this drawing it will depend on the kind of media you are using, your patience, how many time your will revisiting your images, each time bringing a new level of details.
If the hand turned out well, it could be used as model for other hands belonging to a number of human characters.

The hand are too big and they look like gloves, but they can be scaled down and their color changed.
