Weekly Challenge #69: "UMT v.IV: Groovy"

The Diva's weekly challenge is to use GROOVY (a tangle pattern submitted by Eden) in a tangle. I can't say I love the way this one turned out, but I'm trying really hard to get out of the habit of being obsessive about perfection. It ruins the 'zen' part of zentangle when I focus on the things I haven't done as well as I would like, so I'm going to pretend I drew the pattern right (I didn't) and the shading is even (it's not) and vow to do better on the next one. :o)
