Looking through old sketchbooks
I like to periodically flip through my old sketchbooks and see how my style and process has evolved. I go through periods where I draw the same subject matter over and over. In high school, it was facial features and hands. There are some things I miss about the way I used to sketch, and some things I'm happy have progressed. It reminds me to stay loose and doodle for fun more often, the way I used to.
