The tree symbolizes many things across cultures. A few of these representations are rendered in this image:
The human figure is the tree as we are part of nature; arms branched up and out in celebration of life; roots anchor this life to the earth; a suggestion of the crucifixion in the way the legs are gently crossed, and the body appears to be hanging from the branched arms.
I am posting this in honor of the season. I am not completely happy with it and will probably paint over it unless I get a lot of feedback to the contrary! (The sketches looked great!)
