...that your younger art self knew. Is there anything you've learned as you grew older, that seems really obvious now, that you wish that you had learned way earlier? Or are there any things your younger art self stubbornly thought was correct and you've later learned was different? For me it's having learned to "really look" at things. I use other people's art all the time to solve issues I'm having. Not by copying them of course! But by looking at the work of people better than me and reaaaallly learning from it beyond style and anatomy. Also references. Drawing from memory does not win you art points.
