Why is it harder to draw a human?

Answer 1

To accurately draw someone smiling you must master a few things first,

Human anatomy - if you do not know the structure of the face (skull, jaw, teeth, muscles, and skin) you will not be able to make the smile look real. There are numerous books on anatomy for artists, pick up one or two and familiarise yourself with your subjects from the inside out.

Accurate drawing - being able to put down on your paper what you really see, not what you think you see.

Understand the proportions of the face, how each feature fits within the face, and how the features interact with one another when there is movement.

For example - watch someone smile and you will see, that as the smile happens, cheeks move, lips stretch, lines appear by the nose, eyes get smaller and teeth sometimes show.

Shading - the ability to shade something well enough to make it look three dimensional takes practice, and until you can achieve that your pictures will have a flat look that makes smiles particularly look "strange."

You can find many basic books on shading in your library, or book stores, get one that covers many subject matters as the lessons you learn for shading faces will be equally important when shading other objects you draw.

Practice - it is with practice you will learn not only what to include, but what not to include. One of the biggest mistakes made by inexperienced artists is to try to draw all of the teeth in a smile. The overall result is, in some cases, quite disturbing, when it would be so much more esthetically pleasing to "suggest" the teeth with fewer lines and more shading.

My best suggestion is to fill at least one complete sketchbook with studies of faces. Draw everyone and anyone you see. Don't try to get it "perfect," just draw. pick up and read as many books as you can find on portraiture. There are dozens out there, and sometimes you will find a "trick" in these books that will suddenly bring your drawings up a level.

For inspiration let me add this quote from Bernini:

"When making a portrait from life, everything depends on being able to recognise that unique quality that nature give to each person but not to all, and that in choosing some particularity one should choose a beautiful and not an ugly one."

Answer 2

In Art, it is harder to draw a human because humans all look different to each other, and there's the shading, the little details, and you have to get the eyes, nose and lips i the right place because everyone's different, only very few people can draw humans precisely.

Answer 3

Maybe because people try to make simple things harder. They try to make what they're drawing absolutely perfect. Let loose a little :D
