I worked more on the face adding color and darks (still need to do the mouth and chin). I worked on the clothing adding shadows starting near the face and neck. I will shade the clothes darkr near the face and graduate the shading as it moves away from the face. I worked on adding darks and details and shaping to the hat.
Using the same 4 colors only (crimson red, peacock blue, canary yellow and indigo blue) I started adding more darks and details refining the frog. You can see the newer shading on the front and the first few layers on the back of the frog.
