"Sweet George" pen & ink

Looking through an older sketchbook last night, I found these drawings from 2010 of our wonderful George hanging out on the couch next to me. George was sixteen at the time, a graceful sweetheart, all his days. George was a people cat, and we were lucky enough to be his people. He's been gone a few years now, and I still trip over his name now and then when I'm addressing our new male cat, Fred.  Very happy to have found the drawings.  

Blue and White Zones of Light

I teach art project at school along with my math classes.  This week we are looking at the five zones of light, and seeing them to create the illusion of rounded 3-D objects on the two-dimensional picture space.   Each student created a contour drawing of the subject, numbered the spaces according to a 5-value scale, then reproduced the drawing, filling in the spaces as assigned with a monochromatic rendering according to the observed values.   It's our first foray into painting, so some students struggled with the mechanics of using the brush.  But, a number of students produced great results, and were pleased to see the 3-dimensionality of the objects begin to reveal itself.  
This is my quick take on the idea so they could see their expected result.
