I love Christmas! So there is lots of Christmas imagery sneaking into my tiles at this time of year. It's not pure Zentangle because it's way too representational (it looks like something). And of course my use of color veers away from pure Zentangle too. But it's fun!
I used a pink hand colored tile and a purple pen. I highlighted with both a zenstone and a white colored pencil. Shading was added with two shades of pink and purple colored pencils.
