Circles

I was in Chicago this past weekend visiting my sister and her husband and came across this piece at World Market. I thought it was absolutely awesome. 

The circles, the colors, and the overlapping of color blocks. So, I decided to play with some circles of my own. 

These are both made on Cardstock/ sketchbook paper with pens. Just experimenting with black and white circles and then some colors. Circles with lots of details take forever, but well worth it.
