The Diva's Weekly Zentangle Challenge #34, "Opposites Attract"

This is my first official submission for the Weekly Zentangle Challenge on I am the diva - CZT blog. The challenge is Opposites Attract and these were the instructions:

Create your string using EITHER straight lines alone, or solely curving shapes and then fill the string with its opposite!
If you used the straight-line string, fill it with curves and orbs and other soft tangles.
If you used the curvy string, try to fill it using only grid-based and angular tangles.

So, I made one of each. Here ya go.
