I drew 100 Ears. This took longer than I intended. I had some real-life stuff(quite the rarity). Enjoyed my time amongst these cavernous cartilages. Trying to improve my shading. Some of the different angles were hard to get. I definitely used up some erasers with these. I think the biggest challenge was the impersonal nature of the subject matter. Other features are evocative but ears, especially the unadorned variety, are not especially emotive. I think that's why I found myself dragging my feet a bit. All in all, plenty to improve upon, but happy with the practice.
