Why does the sketch look so much better than my attempt at clean lineart? Can I just throw messy lines at the lineart to make it sketchy on purpose?

But it's not just that, I think the face itself was also better on the sketch. It's so hard to make it perfect, I spent like 3 hours doing the sketch face but then I can't 100% replicate it for the lineart
