Time to Tangle with Colors

I am taking an online class called "Time to Tangle with Colors" by Marie Browning.  The first lesson has two projects, the first one is above.  I selected a shape, squares, tangled them with different patterns, I also decided to use the cool colors and then used the dual brush tombow dual brush pens. 

 The second project was using Irojiten Color Pencils, we were asked to use the Rainforest Set of pencils.  I created a Zentangle design on a Zentangle tile and used various blues and set it off with orange, shaded with red.
