If you know someone who draws, and drawings of you end up in their sketchbook.. you are very important
I just felt like saying that.
As an artist I tend to draw fictional characters. Or oc’s I have made up myself. Or just drawings of myself. Any other person I have ever drawn in there has left a special impact on me. It’s essentially letting those people in your “world.”
Not everyone does this, but lots of artists do. And if this happens to you, consider yourself very lucky. :)
