I had a terrible hard time to arrive at the snake in that painting. Usually, objects show up quite easily, and you can see it on our painting of the week very clearly. Most of my paintings are painted very thin, which means you can see every stroke. Also, you would see very clearly every attempt to correct anything. Therefore, most probably nothing is corrected ever.
Every stroke is final.
You can see a horizontal line which serves no particular purpose any longer. If your eye wanders a little more downward, you'll notice a similar parallel line from the nipples of the other woman to the angle in the neck of the snake. These are two hints at something not right at the first stroke. I am very proud of this painting. I lived with it for a long time and know it very good by now.
