Square One: Purely Zentangle Weekly ONE - Yew Dee and Por Fin

This tile combines the last two weekly ONE's, Yew Dee and Por Fin.  I struggled to make a tile I was happy with using Yew Dee, but after reading Eni Oken's ebook on shading, (which can be found here:  https://enioken.com/) I like the 3D quality that can be created with this pattern.  You will also see a little Diva Dance and Daggerly sneaking in from the bottom corners.
