The challenge is to paint the hands simply. Capture the gesture in a painted sketch, paint in the dark values then add the light. Squint your eyes as you look at the hands to see the difference between the light and shadow areas. Keep those values as you paint the correct cool or warm "value colors". Painting in the overall hand shape to start helps to keep it in the correct proportion. Here are 4 hands to be painted on a 6"x6" panel making each hand fit roughly in a 3"x3" square.
Please be sure to follow the spirit and the letter of the challenge.
For example, each submission must be painted after the challenge is posted.
