Drawing human figures is considered to be the most difficult for artists to do. This is because there is no generic way of drawing it. The human figure is unique for each and every one. Hence creating a replica via pen and paper could be complex. Nevertheless, with some practice, you can still learn to draw people.
Learn Proportion
One of the most common mistakes when drawing people would be the proportion. You should take note of this when drawing. The ideal proportion would be 7 heads tall for a man figure. Here are some of the other important proportions to take note of, all of them are 2 heads long:
1. From the kneecaps middle to the foots bottom
2. The femurs head to the whole kneecap
3. The elbows size to the extended fingers tips
4. The collarbone down to the belly button
5. The chest width from each shoulders end.
Observation
Other than mastering the skill of proportioning, you should also learn how to observe. You can have a perfect drawing if you learn how to closely observe faces and people. Being able to observe and view correctly could be helpful in your artistic improvement in the long run....
