I then wanted to add some of the original skin from the frog to form the outside of the skin as well. I opened the original frog image in a new File for easy access. Using the Lasso Tool, I selected edges of the frog's original skin to copy. I copied this selection and pasted it on to our robofrog document. Using the Transfrom-Distort Tool, I transformed the skin to follow the direction of the skin "pull". And like we did in our earlier steps, I proceeded to add slight shadows and highlights to the skin to further accentuate the "pull" effect.
