A shadow can tell you a lot. Time of day is just one thing. When you are drawing the plant it can give you an idea of the structure of the plant.
A path can be trod upon by many things. They leave behind a clue to who or what was there. Do these clues stay forever? No, they are disturbed by the wind, the rain, and the next thing to cross their path. How many different tracks can you find?
There is magic when you visit a place you spent time as a child. The park has changed but the feeling is the same. There are lots of places to sit or gather to eat your food. It is a nice park, I don’t know why I don’t go to Rocky Nook Park more often.
Breaking the rules, the focus point is in the center. The space to the left gives room for the viewer to imagine the wave creeping up to the rocks and leaving the gifts it carries. A rock pointing to the focal point brings the viewer back into the photo were the portion of a plant is left draped over the rock. The cherry on top.
When doing a painting it is often a good idea to study the details to make magic happen. The tree from a distance seems to be gray, but when looked at closer the other colors seen bring light and shadow. Texture is created and interest added with the reddish brown shades you see in the closeup of the bark. Daniel Smith Quinacridone Sienna watercolor might be a good one to use to add a spark to a watercolor painting of this tree.
