Zentangle Challenge #220 - UMT (Use My Tangle): All Boxed Up

This week's challenge from Laura at www.iamthedivaczt.blogspot.ca is to "use my tangle" (UMT), and the tangle chosen is from Alice Hendon called All Boxed Up. I didn't love this tangle at first glance, but once I started playing with it, I had lots of fun - hence the three tiles (smile). My scanner is not great, so I apologize for the quality… really, they all look better in person, I think. I'm looking for good tangles to do on black tiles because I really think I need to start investigating those a bit more, and get more experience with them (and Renaissance too). I think All Boxed Up has potential - and while I like the black tile I did here, I think it could be better if I knew how to bring out the white a bit better. I'd love to take a course just on the black tiles… anyone? (in or near Toronto) Thank you for looking and I know it's very time consuming, but I appreciate it when people take the time to leave comments.
