I can't freehand a circle.
I drew this skull without a reference the other day.

I failed to draw skulls from reference before.
Before this skull I hadn't drawn one in more than a year.

I don't know, just draw until it looks good. And erase it if it doesn't.
And be very loose with your sketch so you don't waste time redoing things that take a long time to draw: nip the wonkiness in the bud.

Drawing the circle perfectly just guarantees better line control that helps with less erasing, but you still need the visual library and some spatial notion.
