This warm-up sketch wasn’t about shape (I took care the kitten in the sketch didn’t look like the kitten in the reference photo), but about texture. And since texture can take a really long time to put onto paper, I didn’t time this warm-up sketch. The challenge was to give an impression of an Abyssinian kitten, while the overall shape was off-model.
It’s fun to explore the relationship of kind of stroke, pencil pressure, blank page (negative space), and the overall impression of the drawing. I see I still have a lot to learn about that.
