(see... told you I was in a bizarre ffvii mood)
Yes, I know that sometimes sketches are Never So Clean as they are in this case... I'll talk about digital inking sometime in the near future in another tutorial. But this is for those who sketch cleanly or who go back and clean up their pencil sketch by erasing and redrawing the lines.
Feedback appreciated! (was it clear? more/less detail? What other stuff would you like to see?)
