Here's page 6. I was never confident with my inks in college, especially since we were usually required to use quills. But in the past year, I've only worked with pens and with shaky hands I've got a lot more control using the pens.
Wouldn't say my inks do much enhancement yet, but at least I've jumped the first hurdle of having confidence inking. I've also given up trying to save my pencils and just end up inking right over them.
