Mellie-Master's Manga Study

Yeah another reason why it's taking me so long to draw is because I'm frustrated. My stylus pen tip is worn down to a.... nub and it's difficult to get smooth lines that aren't too heavy. I need to order more from Wacom, they aren't expensive but sheeesh what a pain in the butt. I think I checked the box it came in before, but it didn't come with any extra tips. =( I can order 5 replacements for $5.
