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.
I recently visited the Dallas Museum of Art to see their temporary exhibit of gowns by the house of Dior. The exhibit includes Dior himself, and the designers who followed him. You have to buy a ticket ahead of time, and they are timed tickets. You have 45 minutes to see the exhibit, then you must clear out for the next group. If you miss your time, oh, well! I picked a few gowns out of the many to sketch. These were, by necessity, done very quickly. I wish I had more time, but, on, such fun!
