These sorts of patterns draw my attention as well. Broccoli look like miniature trees, clouds resemble the patterns of settled sand at the shoreline, a river with its tributaries resembles our circulatory system, a flock of birds, especially when they turn as a group, resemble a school of fish. I'm happy to hear someone else notices these quirky similarities between very different "systems."
I completed the Florida Master Naturalist Classes, and though I enjoyed them tremendously, I remember so little of the vast information we covered. Documenting with illustrations and facts will help me to remember not only new moments/experiences but the details of the marvelous creatures and plants I've seen. I've used online watercolor tutorials this past year, and hope to build skills in this class. I'm thrilled to marry my love for creation and painting.
