This is the beginning of a sketch of my sister-in-law. She has these lovely prominent cheekbones and gorgeous silver hair. Does this beginning sketch look like her? Not at all. I do these practice sketches to warm up, to practice drawing the features, and to become familiar with the current subject. Of course, I want the end result to be a likeness of the subject but if it doesn't achieve that goal it has helped me learn more of what to do and what not to do. Every drawing, sketch, painting is a step forward, even if it is a failure, when we can learn from it.
