Hands still give me a hard time, though.
Don't worry about the hands. Sometimes I can find a suitable hand pose in the Archie comics, and I try to copy it (without actually tracing), but mainly I rely on my own ten fingers. And a camera. However, bending my wrist to get a good angle can hurt sometimes XD.
Some say the famous artist Jacques-Louis David was so lazy with depicting a hand, so he encouraged his client to tuck it in his coat.
Why is he hiding his wrench?
