Both, from life
Recently, at the grocery store, I saw sunflowers for sale. Bought a bouquet of three. It had been awhile since I drew flowers. When lacking inspiration, setting up a still life can be a simple way to jumpstart the creative juices. Here are two sketches, of two different sunflowers. Both drawn freehand on my iPad Pro, using the Sketch Club app, Apple Pencil between my fingers. As a reminder, "drawn freehand" means no image load involved.
