I'm a fan of full lips. Not wonky shaped lips, but just nice, full lips. I think it's because my own lips are thinner, and I always wanted them fuller. Now nicely shaped thin lips like those above on the example above are awesome and on some characters they look great. Other characters require the fuller lips, and so on. It's like an eye color, I guess. Whatever fits best with that particular character is how I look at it. The harelip doesn't do it for me, though. ;)
