....And keep your hands to yourself
Just kidding. I really enjoy drawing hands. They are challenging - but well worth the effort to try and get them right.
Done well, hands are are a visual aid that artists can use to help accentuate the story and emotion they are trying to convey. A hand can be relaxed, tense, fidgity, supportive, strong, elegant and so on....
So next time you are at a social gathering pay attention to the hands....and hey, give yourself a hand, maybe two as well.
