When I look at portfolios, I can gauge the skill of the artist rather quickly by observing the way they draw hands. Expressive hands can add tremendous impact to a pose or gesture. After the eyes and mouth, the hands are one of the main indicators an audience looks for when trying to read a character's attitude, yet so many young artists are loathe to draw them. But draw them you must!
Hence this post...
This is the way I think of hands when I draw them. A wedge and cylinders.
Grouping fingers together and varying their direction can help make them look more natural.
No matter if they're beefy hands or slender, it's still a wedge and some cylinders. Try it.
