Adam & Eve Progression

After a few doodles,this composition sketch
seemed to express the idea best.

In the initial block-in I drew the figures, tree and background
with loose washy strokes of diluted oil paint, over a canvas
panel pre-toned a cold turquoise blue . The main goal here
was capturing the telling attitudes and gestures of the "actors"
and arranging the shapes of the composition effectively.

Here details of form, structure and modeling have been
added--the snake's gesture has been sharpened, and a bit
of anatomy built up in the figures. The tree structure is
vague, and the color and tonal scheme is still undecided.

Now the entire picture has been lowered in tone and the
contrast heightened to focus attention on the characters,
especially Eve and the Snake. I've adjusted details of acting,
anatomy and pose; the snake's hands and body, Adam's right
arm, Eve's face and hands, and I've repositioned Eve's legs
slightly. The structure of the tree is better. One more good
painting session may finish this piece--it needs a final pass
to harmonize tones and color, and add subtle finishing details.

A while ago I was invited by my friend Bill Wray to join him in a show of cartoony humorous animal paintings at Lunar Boy Gallery in Astoria, Oregon. I did seven pieces (view images here), but didn't complete this Adam and Eve picture because I decided to exclude human animals from this set of paintings.
Above are snapshots of this fantasy image in progress--I need another session or two to finish it, I'll post them as I proceed.
