I’ve gotten some guidelines from the book Watercolor Pencil Magic by Cathy Johnson, now out of print but available on cd and download. I got it from the library — great source for out of print books. Last night I did this heron exercise last night with watercolor pencils then did the detail in colored pencil. I still liked it this morning. Next I’ll try another with body and legs, I’ll go heron watching on Sauvie Island.
Cathy Johnson writes great, user friendly guides for drawing, painting and journaling. She does wonders for your confidence and enjoyment of the process.
