I tried another exercise in Drawing Lab: draw 20 cats from your imagination while sitting in bed. I drew rabbits instead, and I had so much fun with this. I learnt a lot too, especially about what eye and mouth shapes make what facial expressions. I like best the blobby shapes rather than clearly defined shapes. I rendered some of them with quite a bit of detail - pencil shading and polkadots. When I'd done them I didn't like them much. But when I came back later with fresh eyes they ended up being my favourites.
