I decided to do a quick watercolor pencil sketch before I got ready for work.
First the shape, then the laying down of colors. The point of this was to be quick! I just chose colors I thought would work – about 5 or 6 pencils.
Final result. I used a small round, and worked the lightest areas and moved into darker. Where I needed more contrast or detail, I used the pencil in the watery areas.
Total time: about 20 minutes from beginning to end. Below is each step.

What a sweet frog.
Thanks, Sharon!
