First, removed hand from background using pen tool. Cleaned dirt off hand using clone stamp. Found pic of snake and added it. Erased parts of hand and cloned to make a more natural fit. Found a background that I thought looked good and resized it to match the hand and snake. Used levels on each layer to try to get an even tone. Added a drop shadow under hand. Burned and dodged where needed. Added gaussian blur to flowers and rocks to make them fade into the background slightly. Flattened image and added lighting effects. Used a slight blur around snake.
