I don’t know what they have to do with each other, but sometimes two things just end up in a sketch book side by side. The woman is drawn after a Renaissance sculpture at the National Gallery of Art and the duck, I think it’s from a Cloisonne figurine. But I don’t know why they are together or why they look in the same direction.
So, that’s why you draw. You do it because you have whimsical ideas that come into your head for reasons that afterwards you cannot fathom. A drawing is a record of thoughts. And sometimes you should just think them with the tools and not ask why, but let them appear. It’s like a leaf falling from a tree or a dandelion sprouting in the grass. You just let “because” be enough.
