Annotations can replace the need for a clear and accurate sketch.

Annotation provides further explanation or clarification on what is not visible in the sketch.

Render - to add details like shading, texture, and depth to a drawing to make it appear more realistic
Annotation - a comment added to a diagram or image to provide explanation, clarification, or extra information
Tone - the lightness or darkness of an area, which helps create a sense of dimension in the image
Texture - how something feels or looks like it would feel if touched
