DRAWING EARS

On the left is an attached ear with no sizeable lobe (and the front angle is quite vertical), and the one on the right has quite a decent lobe (and a front angle towards 1 o'clock). Note that some people have lobed and others have lobeless, where the ear attaches near the jaw with no little floppy bit.

Start with the outside C, G or g (or the letter in reverse as this one is). observe as well the verticle angle along the front of the ear

When about to draw an ear, I always think of a G, or back to front C or g with a Y inside it. Some people imagine a ? with a y inside. To draw them, you don't really need to know all of these names below, just the variations of shapes and how they fit together in a standard way.

Either way, the best way to learn to draw ears is to look at lots of them and note the things that they have in common and the things that may make them a bit different. (are they lobed or lobeless or in between?, do they stick out, what is the distance from the y shape to the outer edge, etc)

Here is one with a semi-attached lobe, try to do a line drawing of this one in your visual diary, note that the vertical angle is slight and the free lobe is small

This one also has a little lobe, a rear facing vertical angle and is facing the other way. Try to draw this one and this time, use a paper towel and rub the  first shading all over, add then add some more shading into those dark areas where you see it and lift out highlights with a sharp corner of your gum eraser (or your battery operated eraser).

on a tonal scale of 0 to 8, there might be every value represented to some degree. Dont be afraid to bring out the big guns for those darks(8 or 9b). Some people like charcoal because it is darker and does not have that silvery finish in the light that graphite has. I have never liked charcoal(messy ++), but you use the medium you like the best.

HERE ARE SOME MORE EARS BELOW TO OBSERVE AND PRACTICE

This one has quite a large flat space between

the y (antihelix) and tubercle (outer rim)

Here are some front views to practice also,  where the anti helix (the 'y') can be seen protruding laterally (more in some than others)

Here is one from behind and one that sticks out more

By the time you practice drawing all of these ear types and angles, you should be able to invent an ear and make it look realistic.

Just keep visiting the ear and draw it over and over until this happens for you.
