I just discovered Dyanna Wolcott. She is a published author and an illustrator of children's books. Some of the published credits of Dyanna Wolcott include Rain Romp: Stomping Away a Grouchy Day by Jane Kurtz and Dog Days: Rhymes Around the Year by Jack Prelustsky.
I particularly like her illustration for I Am Me written by Karla Kuskin. The illustrations are full of wonderful colors and positively undulate along with the rhymes in the story.
I came across an illustration of hers for The Present—A Gift Of Inspiration Affirmation And Contemplation on Dyanna Wolcott's G+ page, but it isn't clear whether this project was ever published. I love the colors, composition and texture of this image.
