Just wanted to blow my own horn. I threw together a new ID for Deviantart, because I wanted one to reflect my current beardiness. Here are the inks:
And the fully-colored version:
Take a look at where the beard meets the hair, in both versions. In Illustrator CS, making colored lines - or "color holds," as I believe I've heard them referred previously - is a bit more of a challenge than it is in, say, Photoshop. It requires some patience, forethought, and in many ways, a "well, looks like you're gonna have to do that all over again, because you messed up, buddy! mindset. It's Satisfying, but tricky.
Imagine throwing a gradient into that. That complicates things a little bit.
So look at and appreciate the beard-to-hair transition. Because it was hard. Yes, I would love some cheese to go with my whine.
